Graham's answer will do if you want a different watermark on every page. If
you want the same watermark on more than one page but not all, insert
section breaks where you want the watermark to change, then unlink the
headers in the sections and anchor the appropriate watermark to the header
of each section.

How can I insert different watermarks in a Word document? I know how to
insert the same watermark on all pages but I would like to have different
watermarks on different pages.
