"Append Folder Name" isn't an option in the Bulk Rename Utility I've been using (2003), but I just visited their web page and downloaded the most recent version and, yes, there it is!

It doesn't completely automate the process, but it does reduce it to a few clicks per folder.
Many thanks for the tip - I sometimes for get that even free utilities get upgrades from time to time.
