Feature request: configuration for joystick gates/deadzone when mapped as buttons

[AtomicShroom]

I would like to request for a way to configure a joystick’s gates/deadzone/sensitivity when it is mapped as a button.

For example, I mapped the N64 C-buttons to a joystick on my 8bitdo controller and it too frequently picks up an unintended direction whenever I push it, due to the gates being too close to the center.

We need a way to be able to adjust this.

Thanks!
