It sounds almost as impossible as some of my users' requests. i.e. "I lost my file. I don't know what I named it or where I put it but I'd recognize it if I saw it. Can you restore it from tape?"Sorry, had to vent. After all, I can't with my users. They're always right, you know.
Seriously though, I haven't a clue. But sounds like a good topic for the Suggestion forum. At the least this will bubble this thread back to the top.
