you should do a data dial while in there too.
this rotary switch (NOT AN ENCODER)

can be placed in parallel with the +/- value switches.
turn the knob cw and value goes up,
turn it ccw and value goes down
easy, just find your select line for those switches, place it on one side of each switch, then other side to the proper cath side of the diodes linked to the data bus.
no extra logic or circuit needed
it's not a cheap switch, but even at $15 shipped it is a fair price for a cool mod that's easy to install.
you can't change the numbers too fast though, skinny knobs can be turned too fast, having a fat knob will help slow down the turning.. guess that's why early encoder data dials were fat too.. to make you slow down.
see it on my HAWK
