Maybe I want Word to automate something that it won'do, but I'd be delighted to be wrong.
If I start a large document, with Heading Level 1 chapters, I can format a TOC and auto-format page numbers of the Ch5-P1 form.
To make the Chapters Word Level 3, which properaly converts to SOL chapters, and then have L4 and L5m do I need to write the single narrative, and then convert a chapter at a time?
