ALT + MMB rotation in viewport

I am just starting with UE4 and so far it looks amazing but i have one quite simple question about viewport control. Is there a way to control view rotation with ALT + Middle mouse button (like it is in 3ds max for example)? So far this is controled by ALT + Left mouse button but is there a way to change it the way i want? I did some google digging but wasn’t able to find suficient answer.

Thanks for answers
