From memory, MS series pedals have a favourites function but the 1 series don't.
Simplest option would be to group your 6 patches contiguously then just use the up/down footswitches to choose between them. You can use ZoomLib to rearrange patches easily. (This would mean you can't easily turn the currently viewed effect on/off. That might not bother you.)
If you want to get fancy (and spend a bit more,) you could add a ZPI, which can have its footswitches allocated to any function you like: random (or sequential) patch selection, parameter changes, effect bypass, etc (or any combination of these.) Also allows external expression pedal (or midi input) control of any parameter. Plus more. Check out the ZPI section of this forum for some information. (There's more to come...)
