I did submit a feature request via product feedback.
I also went ahead and programmed my MC8 Pro for the time being. It has 8 buttons, so I programmed in Stomp A, Stomp B, Combo, Presets, Snapshots, 2 specific presets, and tuner. That is on bank 1 of the MC8, bank 2 could just be 8 specific presets, for example. This has some overlap with FC6 on the Helix Stadium. One thing that is nice with the separate midi switcher is you can stay in Stomp A or Combo mode and switch to specific presets without exiting the mode on the Helix footswitches. One button switching between any modes is very convenient.
