Gamepad Mapping Multi-Button Configuration

[Quan Chi]

I am requesting the ability to have more than one button being able to be mapped to one action. For example, if I want to close the current emu, instead of me mapping R3 to do that, I'd like to map R1+R2+L1+L2+Start+Select to do so. Just an example. Because alot of option you can map can't really be used because there are too many to just have one button mapped to them and eventually it would overlap something. This will solve that problem.
