Actually, it's exactly the same in PDN. Make the rectangle selection, switch to the Black Arrow, hold CTRL, then click and drag to lift a copy. Now, once it's been lifted the first time, you're moving the lifted selection, so you can't lift another copy.
So, it kinda works, but only once. I'm not exactly sure how it works in PS...
yeah that does work...to bad I cant do it anymore then Once
