Page break between a report and subreport

[jaw5]

I have a report with a subreport which both display vertically. Is there a way to force a page break between them if the main report is so long that it forces part of the subreport to the next page? Both the report and the subreport have variable number of lines with column totals for each.

I'm just a report writer, not a programmer so any suggestions about adding code or scripts needs to be spelled out. Thanks in advance for any tips or advice.
