Short question about usage of an expression pedal in peformance-mode (wah or other assignment) - answered! Thanks!

Hi, and sorry, if this question has been answered - I couldn't find the right answer yet.

I have set my Mission EP1 KP as a Wah-pedal in the system section and it works fine.

Is it possible, to assign the expression pedal to different functions in different performances - eg. as a Wah-pedal in performance 1 and an expression pedal for say pitch shifting in performance 2?

I am still running V. 3x as operating system.

Thanks for your fast answer! So it will work for those two purposes.

But I cannot use this on pedal for wah in performance 1 and assign this pedal for eg. number of delay repeats in performance 2 or flanging mix in performance 3. It is either wah or pitch - I would need a second pedal for other assignments?

Okay, that what I was hoping for, but I didn't mess with the newest OS yet. Probably I should.

If you would be so kind to answer an additional question: Are there any disadvantages using the newest OS?
Slowly but steadily I get familiar with the Kemper, but I am still far away from deeper knowledge. That will take some time for me, I guess.

Thank you once again!
So I will change to the newest OS as soon I have time to do it calmly.
