If you're asking what I think that you are, I know one way, thought it is a bit tedious.
Let's say that you wanted to make a snowman. You'd have to go into the object maker and load the sphere mesh. I mean that you would have to hand type it in. Then you would have to do it again. It would spawn on the exact same spot as the first, but you can control it using the arrows and such. You could keep doing that as many times as you wanted, editing it however many times you wanted. Then you could just give your creation a name and place it into a folder. You don't have to worry about selecting anything as a whole, because the mesh maker will read whatever is on the screen as one entire mesh in the map maker. So if you'd go into the map maker to add that in, you would still have your snowman/lump o' rocks.
Hopefully that was indeed what you were asking and that made some sort of sense xD
