Litchi Mission - Copy and Paste from Another Mission...?

[Qoncussion]

I am trying to figure out how to take three waypoints from one mission, and insert them into another. At one point they were the same mission - just saved with different names. After a bunch of waypoint editing, version #2 is a superior mission (now) when compared to the original (#1). But, a particular maneuver through a series of trees got a little bit off in #2. I want to grab those waypoints from #1, and insert them into #2.

Possible?

Thanks
