Add A New Row To Matrix Report

Hi ALL,

I'm trying to create a report using matrix report.
I use a simple query like this.

SELECT Catergory, Month, SUM(TotalApp) AS TotApp
FROM Table1
GROUP BY Catergory, Month

result is like thsi
Approved 2007-03-01 00:00:00.000 60198
Approved 2007-04-01 00:00:00.000 59786
Approved 2007-05-01 00:00:00.000 80608
Decisioned 2007-06-01 00:00:00.000 65981
Decisioned 2007-07-01 00:00:00.000 60217
Decisioned 2007-08-01 00:00:00.000 59040
Decisioned 2007-09-01 00:00:00.000 45180

Now I want to add Approved into one row and decisioned into the next row like that. I can easily do row grouping in the matrix. but then I wont be able to add new rows inbetween those groups. I want to add some rows inbetween those groups to include calculated fields.

I try to use something like this;

=IIf(Fields!Category.Value = "Decisioned" , Fields!TotalApps.Value, " " )

But It gives the same result for every group.( does not matter whether its decisioned , Approved or smthign else)

can any one tell me how to do this?

Thanks
