Drag n Drop Objects in Flash vs. Rev

Over the Thanksgiving weekend, I perused this month's issue of
MacDesign, and found a cute Flash MX tutorial for the holidays. The
final Flash movie displayed a bare X-mas tree with several glowing
ornaments on the floor around the tree. The user could click on the
ornaments and drag them onto the tree, effectively "decorating" their
own digital tree. The tutorial covered implementing the drag-and-drop
functionality through the "on startDrag" and "on stopDrag" ActionScript
events, and how to give each ornament a cool-looking pulsating glow
effect (essentially by creating a motion tween in which the brightness
of the ornament object continuously loops from low to high).
Reading the tutorial, I couldn't help but think what a neat little
holiday toy to build and share with family and friends -- perhaps with
my own embellishments, such as falling snow, an on-off switch for the
tree lights, and a holiday music soundtrack, of course.
I built a first draft in Flash MX 2004 in about 4 hours, including
actually drawing the tree and several different ornaments within Flash
itself. I'm no Flash expert, but the tutorial made it easy.
For kicks, and because I thought I could do a much better version of
the same project (probably in even less time), I decided to try to
build the project from scratch in Revolution. Unfortunately, I ran into
difficulty right away when I realized that there seems to be no built
in handler to implement drag and drop functionality for Revolution
objects. I checked the documentation, but couldn't find it anywhere (as
far as I can tell, the "drag" and "drop" commands in Rev relate only to
dragging and dropping text into fields).
Can anyone point me in the right direction? Do Rev objects have built
in drag and drop functionality, and if so, how is it accessed?
