Lol, did you just answer your own post?
I haven't run across such a command, but you raise an interesting question. A quick search through the alias list didn't pull up anything, but I did find a hidden way to do it.
COPY:
Basically if you copy an object normally it will pick the bottom left corner as the default insertion point. If you use the "copy@" command then you can choose the insertion point which you want to rotate around later.
Here is where it gets tricky.
PASTE:
When you use the paste command it asks you to "Specify destination". If you type "rotate" (or "ro" for the shortcut) as the destination point then it enters a secret mode and allows you to specify a rotation angle. Voila!! Specify your angle and then place your object wherever you want it.
PS
I could only get this to work by typing out "rotate" or "ro". I never could get it to work by using a shortcut key combo for rotate or by clicking on the rotate icon while the paste command was in progress.
Thanks for the new trick, and hope this helps.
