[request] Survey (Grid) disable cam distance trigger between turning points

When you fly a survey with the AutoWP function Survey (Grid) you need to set the cam_trigger_distance to 0 manual and again to your desired value between the turning points to avoid bad shots an unnecessary pictures.
My MissionPlanner looks like this after editing the mission. Can this be done automatically?

This function is interesting for planes, not for copters.

No file, test, or entry point is named. Reproduce a Survey (Grid) mission for a plane with camera triggering enabled, then trace how turning points and cam_trigger_distance are generated. Done means the mission automatically disables camera distance triggering between turning points and restores the requested value afterward, without requiring manual edits.
