Button Input easy fix that would help me

My only issue with POE2 at the moment is this

Allow me to use a different button/key (NOT RIGHT MOUSE BUTTON) to select an orb/scroll/currency/gem to apply it to an item or gem

I am weird, I use a different movement system than most, and my right mouse button is for moving forwards (ok, kill me). Anyway, this means that if I want to apply an orb to an item in the stash, my character moves forward and closes the stash. Please, Please, Please allow me to map that function to a different key.
