Can I date-stamp my documents ?

I have seen a 2010 post about the possibility of date-stamping documents (useful for bills, versions, tax stuff). Right now I rewrite the file name to include a date but that seems a bit tedious. Has this been implemented yet ?

Thks !

The only possibility is still AppleScript, e.g. Scripts > Dates (or Scripts > More Scripts > Change Date).

Thanks. I would like to make that a request, being able to easily add a reference date to any doc. A pop-up menu with some sort of calendar would be nice (the IA engine may even try to guess the date from the content, maybe make a few suggestions, might be easy for receipts, tax forms and research papers).
