[idea] Locking buttons on "pressed"

[CocoBZ]

I want to enjoy playing racing games on PPSSPP, but there's a problem that bugs me. Acceleration requires keeping a button constantly pressed (X in NFS titles, if I'm not wrong). However, the touchscreen becomes unresponsive after a few seconds of continuous pressing, so the car suddenly starts to slow down.

The solution I see for this issue is adding a switch on the screen. This switch would be assigned to one of the gamepad buttons. Press the switch once and the button to which it is assigned is locked in the "pressed" position. Press the switch again, everything goes back to normal.

Is this an option that could be implemented in the future?
