Ability to make the "shift + left-click" functions on a different key

Hi! I just wanted to suggest the ability to change which key(instead of shift + left-click) holds all the functions left click used to have after the newest auto attack on left click feature that was added. I was one of those people that "hacked" the game and instead of making all those functions on shift + left-click, I made them on middle mouse button. Are there any plans for added options for this key bind? Thanks!
