Question regarding G15 keyboard

I have some very spammable abilities. Like lightning bolt. Or steady shot. Or frost bolt. And I usually have them bound to my number 2, and every time I have to keep pressing number 2 over and over and over again. Like 2 22 2 2 2 2 2 2 2 2 2 2 2 2 2 , you get the point. That's very tiring to my fingers and also wears out my keyboard. I want to know, if I program my G15 keyboard so I can just press and hold number 2 key and then my lightning bolts will keep on firing, is that allowed?
