I run with a USB SNES controller and sometimes the game detects me going diagonal when I dash instead of going right/left. I had an I idea to bind right/dash to my Right bumper and left/dash to my left bumper. Would this be allowed? (I use joytokey for my controller to work so the binding would go in there)

Due to the movements of the dashes requiring quick button presses, I cannot tell the difference between each yet they look visibly different. Can someone explain the difference in words?
