If you have a set of pieces that you would like to make a sub assembly then click and hold and drag to one of the upper corners. It's been a while since I was in the editor, I can't remember which. But one corner is for sub assembly and the other is to delete.

Select the wanted part/parts and drag them into the upper left corner of your screen.
