Map editor wish for future patch (MM please read)

[Q]

First I would like to thank MM for this fabulous tool of the map editor. I really love it and had very few problems with it so far.
Now to my wish: To be able to save sigle (star) sytems and to reuse them in other maps.
As many others I've created a earth solar system, that I don't like to build again from zero in every map I want to use. Other examples are special systems as starting points for defined races.
I don't know how hard it is to program this and of course the warp points would have to be omitted. But it would make the fantastic tool even better!
