Is a continuous document possible?

[Conifer1]

I have a 16 page document that is in sections with text, photos, diagrams, links and hyperlinks. Because it is in sections that need to stay together, it means that there are sometimes big gaps at the bottom of some pages. Is it possible to create a document that is one continuous document that can then be exported as a PDF?

big gaps as in page margins> or just not enough material on that page to fill it reasonably?

Not enough material, so a gap at the bottom of the page, then the next section is too big to fit on, so it has to go on the next page leaving a gap. See photo.
