I have a SQL report that contain a Matrix (Example of Matrix fields)

                                 CallStatusType
                          NumberOfCalls %

HandlingOrg SubjectName
              SUBTOTAL

Explanation:
"HandlingOrg" and "SubjectName" are Row Groups in the matrix (the result is dynamic according to the dataset)
"CallStatus" is Column Group in the matrix (the result is dynamic according to the dataset - the matrix will create column for each StatusType) that contain 2 sub columns : "NumberOfCalls" - number of calls for each status type and "%" - The percent of calles in this status from total of all statuses.

I also defined SUBTOTAL under the "SubjectName" group

Example for output:

                   Open Close Watting UnClosed

Org1 Sub1 10 25% 10 25% 10 25% 10 25%

        Sub2 2 20% 4 40% 0 0% 4 40%

        Sub3 0 0% 0 0% 1 100% 0 0%

       SubTotal 12 45% 14 65% 11 125% 14 65%

Org2 Sub1 ...
        Sub4 ...


As you can see, my problem is in the SubTotal line!!
It's correct to write 12 (total of 10+2) BUT!!! it's also operate totals of the percents (25% + 20% = 45%) And it's not good!!! I want it to be the percent of 12 from the total calls for Org1 (In this example I want it to be the percent of 12 from 51)

1) Is there any option to handle value of this subTotal?
2) If no, How can I at least to make this value not visibale only in the SubTotal cell of the percents?
