Somewhere in the darkest reaches of my mind is a memory that Martin Baker of Digital Heaven was going to develop something that did this. It might be worth contacting him via his website. It would be interesting to find out if you have any success. You might also be able to do something by editing the edl. If you could change all the reel numbers to be the same reel using find and replace (maybe using wildcards?) you might be able to cut up your re-imported clip.
Matt.
