[Request] Allow multiple button assignment

[mrtrash]

Hi, I would like to ask to make multiple button assignment for single pad/keyboard button possible. This would allow i.e. to assign 3xPunch/3xKick in fighting games to a single pad button in 'alternate settings' and would be awesome feature. I imagine this shouldn't be a lot of coding work and i would greatly appreaciate it.

Thank you in advance
