Multipage form, "keep with next", expandable

I am creating a form that has expandable fields and allows page breaks within content.  That is not a problem.  However, the fields will not all fit on one page.  Fields one-sic are on the first page with the remainder and the signature block on the second page.  When the fields on the first page expand beyond the page limits it does not "keep with next" with fields that are located on the second page. How do you create a multipage form with pages linked to "keep with next"
