Several ways. You can use a sections and have a section before the unique
footer, a section for the unique footer, and a section after the unique
footer. Use insert>break>next page to insert section breaks. If the unique
footer is the first page, use can use File>Page Setup>Layout>Different first
page. Or you could use an IF field. Say your unique footer text needed to
go on page 5. { If {Page} = "5""Your unique footer text""Normal footer
text"}
