Roll camera while Oculus Rift is used

As the title suggests, I want to rotate the camera view (specifically roll) while the oculus rift is activated. The problem is the function “add roll input” does not work as the oculus rift rotations override the rotation. I noticed the oculus rift has the function “Reset Orientation And Position” which zeroes out the oculus rift and you can optionally add a yaw value. What i would need is a roll input but changing the function to have roll input has yieled errors.

Does anyone have a work around or suggestion that I can use?

Thanks,

Derek
