Multi-level group/sort not showing subtotals
I have a report that displays time entries. The report is first grouped/sorted by Customer Name, then grouped/sorted by Project Name. After the end of each Project certain fields are totaled, however, if a Customer has multiple projects, there isn't a similar row of "totals" for the Customer.
Example:
Customer A
Project A
Entry 1 Cost $100
Entry 2 Cost $200
Tot Cost $300
Customer B
Project B
Entry 3 Cost $500
Entry 4 Cost $200
Tot Cost $700
Project C
Entry 5 Cost $300
Entry 6 Cost $500
Tot Cost $800
Tot Cost $15,000 (this is the line that is missing)
Customer C
Project D
Entry 7 Cost $400
Entry 8 Cost $300
Tot Cost $700
Is there a property or feature I'm missing that would not only show the "total" line after each Project but also after each Customer?
