Is your feature request related to a problem? Please describe.

I've been using the Nintendo Switch joycon in linux, but they require some manual mapping and axis needs to be inverted when used in split mode

Describe the solution you'd like

I would like a way to invert the direction of the axes (e.g. moving from left -> right becomes right -> left and same for vertical axis)

Describe alternatives you've considered

Why this is an issue?
You can just map right movement to the action linked with left (for example for some games with WASD movement scheme you can map left to D instead of A)
