How to make a component of a character use control rotation with an offset

Hi all,

I want to make a view mode where the character can look at them self from the front rather than the back. However, I still want them to be able to adjust the view angle slightly so I need to have Use Pawn Control Rotation enabled on the spring arm. However, use pawn control rotation means I can only ever look at the back of the character. Is there a way to add a 180 degree yaw offset to the control rotation just for my spring arm?

Thanks in advance
