Is it possible to bind "look back" and "move head left" to the same key?

The head movements “Look back” and “Move head left” only work when they are binded to separate keys. If i bind them to the same key, when I press it, the camera looks back but does not move the head left, however, if I bind them separately I can look back and move my head left at the same time. Is it an intended feature to not be able to bind them together? Also, I’ve tried binding the “enable” button together with the two actions and separately but it doesn’t work. Move head right doesn’t work either, I’ve tried turning on relative control and changing the multiplier but none of that worked. Edit: I just used an axis instead of a key so problem solved.

I dont know about having them on the same key, but I believe you can have them bound to the same axis

Thanks but I want them bound to the same key not the axis.
