Identifying overrides

[Nancy Allison]

Hello, all. Have gotten caught up in minutiae but didn't want to leave 
this discussion hanging, since you have all been so helpful. I have 
given up temporarily on the overrides stuff, since there are more basic 
things I must fix.

Anybody know how to replace tags at the book level? I've replaced some 
cryptic tags with descriptive names. I do not want to replace them 
chapter by chapter (total of 20 chapters), by going into the Paragraph 
Designer and using the Global replace option for each of the 12 tags. 
I'd much much rather do it at the book level.

Possible?

Thanks again, very much.
