WISH: More options in Custom Press and Hold Mode

[nickstomp]

If you set the AM4 Press and Hold Mode to Custom, you can only access to the press and hold function of the single switch.
In this way 4 switches are not enough.

I would like to be able to customize also the following switch configurations:

Switch 1 & Switch 2 Short Press:
Switch 2 & Switch 3 Short Press:
Switch 3 & Switch 4 Short press:
Pedal 1 and Pedal 2 Short Press

Possibly also
Switch 1 & Switch 2 Long Press:
Switch 2 & Switch 3 Long Press:
Switch 3 & Switch 4 Long Press:
Pedal 1 and Pedal 2 Long Press
