Using condition yaw on auto missions, POSSIBLE?

Has anyone ever tried command CONDITION_YAW during mission with VTOL plane, while flying in VTOL mode( copter)? I tried and it said unknown command in messages.
Am I doing something wrong or there isn’t/is a way to condition yaw with quadplane?

Its not one of the supported commands for arduplane, though I wish it was in light of the q-plane subset and I second the need for this modification.

see the list of supported commands here:
