Long Press midi command without triggering normal Press

I use a Morningstar MC6 for reference with a Line6 HX Stomp.

I want to setup my MC6 as such:

Bank 1 = Looper functions

Banks 2, 3, 4 = 4 favorites + Snapshot Up + Snapshot Down functions

One of the Snapshot functions, on Long Press, will also trigger the Tuner

I first tried with the Snapshot Down first on Press, then Tuner on Long Press, then Snapshot Up on Long Press. This way, using the Tuner automatically puts me back to the original Snapshot (the HX Stomp only has 3).

Then I remembered I could swap the commands: the Long Press for tuner first, and then the normal Press for Snapshot Down.

Problems: * The second solution here did not work. The Snapshot still gets changed * I also don't know how to make either 'Tuner' or 'Snapshot Down' display on the Midi unit, base on whether I used a Long or normal Press trigger...

Any thoughts?

Another issue I couldn't fix in my Midi adventures: using the Record command on the Looper automatically triggers the Play command. I may be able to go past it by... not having a Play button, and having a dedicated Stop and Undo button, rather than Toggles. To-be-tried. This is most-likely a Line6 thing rather than MC6-related!
