For now...why don't you just SEARCH for the Jeff (or Ed) files, then use an empty IPTC field so that you can use any naming convention you'd like.
I would search them, then use Catagory and Supp Cat 1, 2, and 3 for a) shooters name b) hold the ORIGINAL FILENAME {filename} or {filenamebase} or {frame4} and c) session d) mat
Does this make sense?
