Aligning text in a trailing summary to the bottom

[Quartekoen]

For my invoice table, I have a Trailing Grand Summary part. All it really lists is the total for the invoice, but it's important that this total be near the bottom of the last page (above the footer). Being a trailing grand summary, it already appears on only the last page as it should, but is there any way to cause it to appear at the bottom, instead of right after the invoice's body? I can expand the height of the summary, but since each invoice is a different length, it sometimes jumps to the top of the next page.
