Splitting Mission in to different pieces

Hi There

I would like to find out if it is possible to split a Survey Grid Mission that you have created in to separate missions.

What I mean is, that if the Mission is to long for 1 flight then you can split it in to different Missions without having to go and draw the Polygons over.

Thanks

I save the mission using another name, like AM1 and AM2.
For AM1 I delete the last half of the waypoints and save it.
For AM2 I delete the first half of the waypoints.

It helps if you make the end and start points between AM1 and AM2 close to Home.
