Quadplane VTOL_takeoff - behavior in auto missions

Does anyone have experience using auto missions with a quadplane?

The logic behavior of when the quadplane transitions between modes is not obvious. I am aware there are some configuration options in Q_options but none seem to give the desired result.

I only want the quadplane to transition when I explicitly tell it to.

For example, VTOL_Takeoff should take off and then move to the next waypoint as a copter, it will only transition when it hits a Do_transition command.

The reality is that as soon as VTOL_takeoff is complete the plane transitions immediately. This is not the behavior we want.

Is anyone aware of a way of preventing transition after VTOL_Takeoff?
