It can be implemented, but requires new clients and a new release of PO and stuff. It also shouldn't be terribly difficult, but getting any of the PO coders to give it any priority would probably be tough. That said, I am on the programming push list for PO, but what with stats and other massive undertakings I am working on, can't really invest much time into it at the moment. Maybe I can work something out with coyote for the next PO release. It would certainly not happen for awhile, in any case.
