In case it helps, here's a one-pager I've made. As you'll see, it uses custom styles so that both headings and paragraphs can be numbered driven by a field. If that works, all you have to do is make sure they don't start on the "future" sections before the requirements doc – and, thus, the numbering – is locked down!
