If you push a single Stomp or Effect knob or the general Stomps or Effects knob u can select Presets with the browse encoder.
On this screen, it would be great to have a "from other Rig/Performance" knob. After pushing the knob u don't see a list of saved presets but a list of Rigs (all rigs from browser and performance mode, the ones used in performance mode could be named "Performancename Slot#"). After choosing one, the slot (or whole stomps/fx section) u pushed in step one gets the configuration from the rig u have chosen now.
That would be great.
