Hi! Can i bind actions Save/Load State, Overlay menu) to pad button?

Now i use pad in android launcher for run “RetroArch”, use for navigate and run rom, but if need save state i use IR remote from my TV-BOX for select overlay menu an use pad for select “Save state”.

I try finding in menu bind but find only bind for standart gamepad button, no system actions.
