Go Forth and add REVERSE! (Please?)

Amazingly, I seem to be a minority of one in wanting a feature common to many direct drive t.t.s as well as the GUI on DJay desktop up to V.3 (and still MIDI assignable to any controller thereafter): REVERSE Playing Direction. It’s really a pretty BASIC, and Common feature to most soft decks, even on iOS apps. Why the hold-out? (Or am I missing some very obscure setting feature that will make it possible either on the UI or in MIDI assignment?)
