Metadata in PDFs

Hi all,

I really want my team's exports from Illustrator, InDesign etc. to include metadata by default.

Ideally, I want the filename and the designer's name (or login details... some kind of identifier).

I don't want this to be a manual process - they'll forget. I don't want 3rd party apps ideally.

Am I asking the impossible? Any help would be awesome.

Richard.
