To add a Page Break:
create a Paragraph Point
In the Paragraph Body enter:
Make sure there are no extra spaces or anything before or after it.
Set the Paragraph Label to "Page Break" or similar so you can search for it and see it at a glance.
KEEP IN MIND: the document output is dynamic - every Interviewee is going to provide different answers, and those will make the length of the various pieces of text unpredictable. Page Breaks can cause pages that have just one sentence and a heap of blank space... so test thoroughly.
