Thanks for the help, friends. I actually contacted Glen (video above) to ask how to configure the helix like he does in this video...where he can toggle on/off stomp FX while still in preset mode.
Global settings, set preset mode to BOTTOM FOUR (or top, whatever your preference) foot switches. Then, you can MAP stomp fx within the active preset to the other four foot switches, while still in preset mode.
I have my bottom four FS on my four most used amp tones presets. Then the top 4 set to my most used fx ( I have the same fx saved to ALL of my amp presets in the same location). Kinda feels like a blend of stomp & preset mode
