Another question about importing SVN with fast-import

First off, I would just like to say fast-import rocks. It's well named too ...

Now the question. Shawn recently added C and R operations - almost as soon as they were asked for too. However, how do you copy a file from a particular revision? I have just hit a point where someone deleted a directory, and then copied one of the files from that directory back from an old revision (as two separate commits). Since I'm not tracking any branch contents in my front-end, and the copy operation only works from the current branch head I seem to be stuck ... or have I missed something?
