Update all files in a Book with a Paragraph Format?

[Amy Harvey]

Is there a way to update all files in a book with a specific paragraph format?

We have a Para Tag called "Revision" which marks the revision number in the footer of the document.

When we go to a new revision, we've bee importing the paragraph format into each file in the book... thus having to open each file individually and either change the master page (where the tage is stored) or change the paragraph tag itself with the correct Rev Number.

Any way to do this.... for example, like a global property, etc?

Thanks
