Update! Nick Murdick got back to us after the recording with the answer to a question he wasn’t sure of at the time.

Here’s the answer…

It is indeed possible to convert a derailleur between short cage and long cage at the shop. If you connect to e-tube project through the PC you will see an option to change between GS and SGS. The derailleur uses a different shift pattern for each cassette. In some gears you may notice that it breaks the shift into two steps in order to use the shift ramps on the cassette more effectively. It's more noticeable when double shifting.
