Thank you all for the assistance. I am wondering if the characteristics of the document are making this hard. These are engineering manuals that are several 100 pages (between 500-1000) long and have many bespoke styles in them.

I need to do some more research on styles and how they inter-connect.

Again, thank you for your assistance and time, and (@Kilroy) I realized you may not have been joking - my apologies if so.

I will keep you posted if I make progress.
