Hi! It's possible to make it so that you can use a controller for this, but would probably require quite a lot of extra work. You can set it so that the "click" is a button press that adds to the total click count, but the menu on the side is a little more tricky. You'd have to make it function more like the default RM menus, so there's always a selection box around one of the options, and the player has to press up and down to select the option they want, instead of just being able to click it.
