I had made a similar ticket for kangaroo paw T10241 and it was added in shortly after.

Upstream issue ticket has been closed, going to close this one as well.

I'll look into it, but it may take me a while to get it right. Currently the TAZ Pro uses a single feedrate for manual moves on E, so it needs to strike a balance between being too slow for unload and being too fast for extruding. This is different from the Mini 2 and Workhorse which does loading and unloading differently.
@marcio On my first test here I got a clog with PA-CF. Would it be possible to increase the rate of retraction after purging? It seems very slow at the moment compared to the successful Mini 2 and Workhorse change filament options. (Tested on 184.108.40.206)
@anolen, merged it to master.
since the last time you entered the change filament screen or changed the nozzle.
Before submitting those tickets and updating the manual for Pro, try the 220.127.116.11 firmware as well. @marcio has implemented the change as described above, and now when just pressing "unload" for the first time when powering up, it will automatically extrude some first. If this behavior works well, we may want to consider writing directions to that.
@karrad We will try the new firmware today and let you know.
@dale Once you have the local PDF updated (and with whatever changes you would like) let us know and we can get that updated on the website. The quick start guides will need another ticket with specific requests for marketing.
The thermistor circuit might be the only one in the harness that could be checked. This means that this fix would depend on the user forgetting all the y axis connectors, or none of them.

@karrad I checked the Workhorse Quick Start and it tells the customer to use the change filament option in the LCD.
@dale Thank you for confirming how the customers are removing the filament. We can now proceed!
@karrad I went back a couple of weeks and we are getting an average of 15 Mini 2 and Workhorse filament change issues a week. Customers have responded that they followed the Quick Start guide for removing the piece of filament used in shipping.
@Dante This is what we need clarification on. While using the Change Filament Option on workhorse we cannot duplicate this issue. Here is a photo of one I just pulled out of my workhorse:
the real root of this problem is the injection molded filament guide piece in the aero (which makes printing flexibles possible with this design). Due to the taper of the injection molded part (necessary for injection molding) the inlet of the guide is a smaller ID than the ID of the heat break and nozzle. when the filament cools in the heat break/nozzle it matches that diameter. now when you go to remove the filament, it is too large to pull through the injection molded filament guide, so a reheat and ram purge is necessary in order to remove the filament through the smaller ID of the filament guide without jamming
The firmware cannot check whether the connectors are plugged in. An unplugged connector, from the firmware's perspective, is no different than a nozzle which isn't touching the cube.
@karrad I think the issue is the out of the box experience when first changing the filament. Reports of the filament being too small or slighted melted, which creates a ball at the end of the filament that makes it almost impossible to get out.
Here are completed importable profiles, please make sure it is being imported into a 3.6.20 or newer version of Cura.
With our requirement to print both flexible and standard materials out of the same tool head, the feed path was constricted on the Aerostruders to allow this. This is what is causing the additional jamming, and unfortunately cannot be removed while still being able to print flexible and solid materials.
@DaniAO the feedback from the summit was specifically stated about the Workhorse and seconded by a couple other channel partners. In further discussion after that, it was mentioned that both the Mini 2 and Pro have experienced this as well.
@DaniAO That is correct the test filament is removed and replace it with a cold piece.
@marcio I like the option that it will load about 10mm and then reverse. Is it possible for TS to test that?
Photos have been taken and product page is up. Closing ticket.
There are two button, "retract" and "extrude" and semantically I cannot have the "retract" button do an extrude. That will be confusing. What I can do is disable the "retract" button until the user has pushed "extrude" to extrude some filament.
@anolen You rock! Thanks for the follow up :) I will keep an eye out for the Profiles so I can send that along.
@Galadriel, I do! I am confirming the high detail settings today (the print is long), as soon as it is done I am posting the profiles (high speed, standard, and high detail) and staging them to be merged into Cura as soon as possible 😄
