Turbo button per-game mapping

Hello,

I’m running Retroarch 1.9.0 on my Android device (Samsung Tab A). I’m using an external bluetooth controller (Wamo Pro).

I’d like to have Autofire on some arcade (FB Neo) games. I’ve seen the way is mapping the Turbo button to the physical (B, code 96 in my bluetooth gamepad) button.

I don’t want this enabled for all the games or all the games of the core, but only on selected games, so a game override would be the solution.

But from Quick menu, under Controls, I can change only remap (from retropad to core) settings. I cannot change Input mapping (from gamepad to retropad). That’s a global configuration I cannot save per game.

Is there a way to configure Autofire (Turbo) in a per game basis? I don’t have a spare button to assign to turbo, and avobe all, I don’t want to have that button pressed all the time additionally to the B button.
