Inserting a section break without a page break

Is there a way I can insert a section break without having the page break?

I need to insert a section break so that my footer can be different on the second page. But I want the page to break in the natural place (I'm doing a mail merge and some letters are different lengths, so there's nowhere I can force a page break and make it look right on all letters).

Thanks for any assistance you can offer!
