[Zope] replay transactions?

One of our Zope administrators blew away some work by deleting an object and importing a new one in its place. I've been unable to undo the transactions. Instead, I have restored the missing objects from a backup. Significant work was done since the backup, though. (It was a long night.) I can see the transactions in the folder's Undo page. Is there a way to get at the transactions and replay them? Thank you. --kyler
