We are attempting to create a master document from several word documents. We insert a section (next page) break at the end of the first document "try" to keep the page/section numbers as created for each document. Sometimes this works, sometimes it doesn't. Our biggest problem is when adding or deleting sections within the created master document, it totally destroys all formatting, page/section numbering and we have to either start all over or go back and modify each page/section.
We are creating these documents for very large project bid specifications and it is typical to have to add/delete sections, pages, from a contract book.
