Just found you can assign pedals "up + down" (when you press both together) to MEM+1 which moves to the next patch and pedals "up + ctl1" to MEM-1. So you can use the individual up, down and ctl1 as stomp pedals and still move through the patches. I've move the tuner (which was "up + down" by default) to the foot pedal button (press foot pedal down hard... force required can be adjusted by another setting) and I don't use the looper ("up + ctl1" by default).
You make these changes in the System menu.
