[Question] Remap 'Screenshot' Key

[sodamnfake]

So far I haven't been able to find the option anywhere for remapping the F12 key for taking Screenshots to something else. Does it exist? The only keys I see are things like Save States and other unused functions. F12 for me is very inconvenient and so is reaching for the keyboard while I play with a controller. It would be really nice to be able to hit a button on my controller to take a screenshot at the right moments, without searching over my keyboard to do that.
