I see how to save a preset into a new location, and I can swap presets the following way, but it is arduous: Save preset A into an empty location; Save preset B into preset A's old location, over-writing it; Save preset A from it's temporary place into B's "old" location, over-writing it. But is there a way to just swap A<->B directly? I found swapping stomp footswitches and snapshots in the manual, but not presets - maybe can't be done?
