assigning multiple buttons for a single function?

[AmuroRay09]

I'm using a gamepad for a windows version of ppsspp and I'm wondering if I can assign the multiple buttons of it for a single function.

for example, I'm gonna set the buttons r2 and l2 of my gamepad to the supposed r function of a psp.

if this is possible, how?

I'm kinda new in this emulator so any help will be much appreciated.
