@Riot: Option to level an ability you have no points in if you press that key

I'd like that if you have a point and you press an ability key you have no points in, it will place your point into it.

Sure there are hotkeys for this, but it's an extra/different button press or combination that you have to do; when you hit one of those early levels in the middle of a teamfight (especially 6 for most) an extra button just reduces your reaction time by a small amount.
