Something cool about track folders I didn't know

So maybe I'm just a dim bulb and this is/was obvious to the rest of you, but I thought I'd share anyway even if it just gives you a laugh.
 
I received a project for mixing that had about 70 tracks.   Typically, I have just dragged and dropped the tracks to organize them and then maybe put them in track folders.
 
Looking at the number of tracks I had I though, I wonder if I can multi select tracks and put them in a track folder to move them?  Heh, it worked.  I know, Captain Obvious here, but thought I'd share.

Yes it is known but it never hurts to report a finding. Who knows someone may not know or didn't think about it.
