Modifying a Block Attribute Across Multiple Files

Hello masters of CAD,

I have a sort of template-like block that I'm required to put around the edge of each layout in all of my files for a current project. A lot of the info is different across files (Building, drawing number, title etc.) but some of it, like publishing date or revision number, needs to be the same. Is there any way I can modify an attribute of a block across multiple files without having to open every file myself?

Thanks in advance!

You can open modify and save as many dwgs as you like automatically using a script

open dwg1 domything save close

open dwg2 domything save close

etc

The domything would be say a lisp or vba that you programmed to make certain changes to an attribute.

I think this has been asked for before search the forum say "attribute" "block update" etc you will get a lot of answers but a bit of time spent could save you hours.
