Dynamic Sub Total Using EPM Functions

Hi Experts,,

I have a report where in the row axis, we have a combination of Flow and Accounts (with suppression)...  what is the best way to include a subtotal line after every Account?  This subtotal line should be dynamic, based on the suppression...

For example:

                                TIME

FLOW:  ACCOUNT:     

F_100   Account 1

F_100   Account 2

F_100   Account 3

           Subtotal 1:     $$$$$

F_200   Account 1

F_200   Account 4

            Subtotal 2:     $$$$$

F_100  Account 5   

F_100  Account 6

          Subtotal 3:     $$$$$

F_300   Account 5   

F_300   Account 6

            Account 1

          Subtotal 4:=SUM(Subtotal 1+Subtotal 2+Subtotal 3+F_300: ACCOUNT 5+F_300 :ACCOUNT 6+F_300 :ACCOUNT 1)

The subtotal lines above should expand with the Flow & Account selection, and should be displayed after every Account..

I tried with EPMInsertCellsBeforeAfterBlock, Member Sorting and Grouping.

Can any one help me on this.

Thanks in advance for your time and help!

Regards,
