I'm trying to add another total to my report. Right now I show Monthly Sales By Region. I want to add another grouping above the regions. I want my report to look like this:
Japan East Region Totals
Japan West Region Totals
Japan Region Totals (includes Japan East and Japan West Regions)
Japan East Region Totals
Japan West Region Totals
Japan Region Totals (includes Japan East and Japan West Regions)
