Adding multiple key bindings in Retroarch

[Bedwyr]

Is it possible to add, rather than replace, key bindings. For example, I'm running a new copy of 1.78 and while I assigned hotkey-enable to R3 on my XB controller stick, I still need alternates for my 8bitdo controllers (preferably the select button) as well as the keyboard. Currently, any assignment I make in the input->hotkey menu replaces the previous assignment.

Practically speaking, I'd prefer the keyboard hotkey assignments just work without a hotkey mode shift, but I can live with a key combo to make F1, Esc, F5 and such work correctly.

Followup. Because I dig into the emulation communities infrequently, I tend to forget a lot in between. I clarified, researched, and posted a question closely related to this one on the libretro forums: https://forums.libretro.com/t/creating-hotkey-alternates-for-multiple-controllers/24093  I'll cross-post any solution here.
