I'm not sure, but recall that from the front panel, you can access your cab block and use the large rotary knob to scroll through the cab library. Is that what you were thinking? (Will need to RTFM to be sure...) The Perform page is displayed as a layout for the 9 footswitches. I don't think you meant layout while referring to a scroll function...that's located on the front panel NAV buttons, not the footswitches...

Not sure if this will help...
