It can't be done directly; each report runs independently, and the result of a preview is discarded once the report statement completes. Your only alterntive would be to create your output to a file and only view the file after the last report completes; if you need to include formatting, you'll need to emit a report using something like the Adobe PDF file format, since ASCII doesn't have a facility to carry formatting detail or graphics that can be viewed on screen.
