Is there anyway to use the page footer band to print totals at the end of a group?

For example, I have a group on purchase order # and would like to use the page footer band to print the purchase order totals on the last page.

I'm not using the group footer b/c they always want a constant height detail band and I don't want to mess around with adding blank detail records.

I'm planning on adding a logical to each record in the report cursor, .T. if the record is the last line item on the PO. Then I can use the print when option of the totals. Just wondering if there was a clever way to do this with just the report ...
