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

Setting Yaw mode to BOTH makes it so that when yawing and rolling the controller to the right, camera looks to the right, however some players (like me 😊 ) may prefer one of these axes inverted so that for example when yawing to the right, the camera looks to the right, however when rolling to the right, the camera looks to the left.

Describe the solution you'd like

The Invert X option should be split into two options when Yaw mode is set to BOTH.

Describe alternatives you've considered

Alternatively it could be implemented as is in the Steam Input settings.

1. To get there launch controller settings for a chosen game and press the little cogwheel button showcased on the screenshot:
   

2. Then scroll down from here:
   

3. You've reached the destination. Here are sliders that allow to invert the axes and also change the proportions of how much one axis should contribute to the movement.
   
   *I am unsure of the other "3DOF to 2D conversion style" options, I've been told to use the Local Space one and it works so I haven't touched the other ones, however it also might be something worth researching and possibly implementing.
