editing multiple titleblocks

Sometimes I'll get a job that involves as much as (50) drawings. Is there a lisp program or anything out there that will allow me to edit titleblock info over several drawings without having to open a drawing one at a time?

I figure it would be similar to a batch print lisp routine like has been posted here at one time or another. At any rate I'm not a programmer so if someone (lisp guru) could point me in the right direction it would greatly be appreciated. Also tried looking at the Cadence website and came up empty.
