Customer Statement like aging with Invoice Suffix - Crystal Reports

AR wants the customer statement report to Group By Invoice Suffix at the bottom as in:

Suffix Current 30 60 90 120 150 Balance Due
IN 100 50 0 (Note there is no suffix for Invoices)
CM 50 0 0 Credit Memo
DN 10 0 0 Debit Note
UR 0 0 0 Unapplied Receipt

The values above would be totals for the Customer for each of the suffixes.

I have spent a lot of time with this to no avail. Has anybody done this, or can you suggest what method to use.

Kind ragards,
