Best Practices for Tagging Files for Translation

Any recommendations on best practices for tagging files for translation -- something that will make it easy for the translators to identify the files they need to pull from RTC to send to the translation team?  I know I can put them in a separate component, but this will also separate them on the file system -- which I don't really love, since these files have a relationship to the ones that are, well, "performing work."  I've also thought of adding a User Property to the files that need to be translated and building a query to find them all, but I haven't tried that yet.

Thanks!
