Is there a way to add a yaw offset to orbit mode from QGC?

I would like to add an option during orbit mode, where the ORBIT_YAW_BEHVAIOR is set to HOLD_FRONT_TO_CIRCLE_CENTER. This option would allow user input to add an offset to the yaw by a maximum of ±15 degrees (i.e. a 1 degree offset from center to the right). Would this be possible without modifying the PX4 Firmware?
