Daniel,
Tyler touched on it above, but to say it a little more clearly …
The aux switches provide the exact functionality you want. The aux switch changes are persistent and independent of one another, they way you want. Setup aux 1 for your distortion (preset A) and your aux 2 for your pitch (preset B). You can even have aux 3 for a program that spans presets A and B. You have three options.
Hot switches and aux switches operate differently so folks can mix and match as they please. Seems like a good system to me.
Good luck!
