I've found the One-Touch feature to be very useful... and yes, you can assign both User Voices and Programs. You cannot select them at the same time to 'access' voices but you can once you're in the EDIT ONE TOUCH mode. Here's how:

* Press SAVE/ENTER.

* Press One Touch Edit (F4). Once in this menu, you can select whatever voice you want within the respective One Touch locations ... including User Voices or Programs.
