You can't do something which is connected by material on the top side, 
so to speak. It should be pretty obvious if you think about it. 
Something hanging from above would have to be hanging in the void until 
the printer have come up to the point where it connects. Objects are 
built from the bottom up.

Or did you actually figure it out, and asked a rhetorical question?
