Exiting RetroArch via controller

I know this isn’t a terribly big deal but in my current setup, I have to use the menu shortcut (mine’s l3 + r3), go down to exit and that puts me back into my front-end. What I WOULD LIKE is to have it setup like the RetroPie, where I just press “Select + Start” and that exits RA and puts me right back into my front-end, EmulationStation. Is this even possible? My overall goal is almost complete. An easy to use HTPC with native gaming environment (i.e. Steam and RA/Emulation Station)

Thanks in advance!

Side note/question If anyone has a nice, easy solution to do this with non RA supported emulators (mainly PCSX2 and to a lesser extent PCSXR), I would appreciate it. I do own xpadder but haven’t managed to get it to exit correctly. Also, if anyone knows, can I put a shortcut to Steam or PC games in ES? I know this isn’t the right forum, so no need to answer if you can’t. I’m just sick of signing up for forums. Five forums in 2 days. lol

Thanks again!
