My idea is to have additional drawing descriptions like the Project descriptions. This way we can have more drawing specific information that can be filled into the title block using title block update. I'd also like to be able to change the name of the these additional descriptions using a similar default_wdtitle.wdl file.
My thought is that these additional drawing descriptions would contain the Drawn By, Drawn By Date, Approved By, Approved By Date etc. as well as possibly doing revision information for per sheet revision tracking.
