This page was written about reorganizing pages but it is really about logical grouping of text. Moving/Reorganizing Pages in Microsoft Word

You want to use your heading styles. You are already doing that in some spots. Each part of your document that you want to keep on one page should:

• Start with a heading style that is set to keep lines together and keep with next.
• Have each body paragraph set to keep lines together and keep with next except the last paragraph of your logical grouping.

To the extent it will fit on a single page, Word will struggle to keep things formatted that way on one page. The problem comes up when you have a mass of paragraphs too big for one page all formatted that way. Word will give very flaky results in that situation.


Note that with the above formatting your headings are all keep with next and keep lines together. If you collapse headings, you may run into the problem I talked about with having too much formatted to keep together on one page.
