Scrollwheel binds?

Is there a way to bind abilities to Up and Down on mouse scrollwheel at all? I tried to un-assign the function from zoom-in/out, to no success... Imagine two of your abilities on your fingertips.. pun intended!

+1 to this. Allow modifier keys (ctrl, alt, shift) with them too of course.
