Hi Jack,
you could use Search & Replace. Enter "1REPORT" into the search box and into the Replace Box.

Now place your cursor before or after 1REPORT in the replace box (depending on whether you want the break before or after that word). Expand the S & R Dialog, at the botton there should be a button Other characters (or something like that), there you can select page breaks.
It will then insert ^m (in the german version, maybe other letters in yours), representing a page break.
