I have a very large assembly that I've imported.  The number of components makes scrolling up and down the tree very time consuming.  I eventually want to break this up into sub-assemblies, but first i want to isolate components into separate folders.  I can do this by dragging parts in the tree, but then I have to look at the screen, see what part I've selected to decide which folder it goes in.

Can I select a part on screen and put it directly into a folder without having to find it in the tree?
