1) Unfortunately you can't change the PDF report look. It's basically a screen dump. What you could do is, is to add "&DataFormat=Excel" (without the commas) to the end of your URL and press enter. It will then allow you to save the report as an excel spreadsheet.
2) You would need to change the report to a SUM for the day to show just the number of flaps. Post up what you have on the Select Fields tab in your report.
