The feature is problematic to implement. In an extreme case the last page may have no space to place a footer: it should force a page break and the trailing footer goes to new page with no content, which is undesired.

As a workaround it you may use a conditional page break to move some content to next page (if needed, to make the last page not totally blank) and a footnote.

The page break will take effect only if the remaining vertical page space is less than 200px (and the last text section + footnote do not presumably fit it)
