MIDI Mapping more features

Hi This is a tiny little request that wouldn’t need much code I think,
but make my life easier and speed up workflow dramatically:

I’d love to quickly scroll through sounds on VSTi instrument properties to find the most suitable sound while playing a pattern. Make the “previous” and “next” arrow buttons MIDI mappable,

I am sure that people also would like other buttons and selectors mappable, but this would be my favorite.

In my way of working, the Advanced Pattern Editor section would also be nice to have MIDI mappable:
