[CodeReviewer] Combine Files in Review Before and After Check-In

I created a new file, and added it to a review before checking it into ClearCase.  I then checked the file in.



Reviewers then had a couple of changes for me to make, which I did.  I added the files to the review.  However, CC sees them as separate files.  Is there any way of combining them into a single file again, so the changes made line up with the original defects?
