Lens Coverage Projection

It would be helpful for planning to be able to see a basic (or advanced) field of view projection for the camera.
I use my Air2S to do visual inspection and documentation of off-road trails and am thankful for waypoint capability. However, planning with waypoints has been tricky for me so far due to the elevation changes and trail angles. A coverage outline or colored area in the planner would really help me adjust the camera to be more effective. I’m not talking about needing 3D projection or any of that just an indicator of what the camera is pointed at if I’m 100ft in the air at say -15deg tilt.

If that’s too much to ask how about an artificial horizon gauge with altimeter/camera angle/etc…
