Track key adjustment mapped to hardware (button/encoder)

There’s a neat bit of functionality that I didn’t even know existed until recently. It’s the “key adjust” feature. In the display of a loaded track, you can touch the key (8A/12A/etc) and then increment and decrement the key (without changing pitch/speed) via the touch screen. Pretty neat! I was curious if there’s a way to control this with hardware, rather than the touchscreen? I’m on a Prime 2, but curious also if it is adjustable with any hardware options.

there are several feature requests created, bigger tactile buttons, being able to use the parameter buttons, etc… check and vote
