Using values returned from SQL for Report column names

Question

I am building reports against our TFS development db.
One of the reports tracks days spent (Dwell Time) in various status categories (eg: New, Assigned, In Development, Hold, etc) for a given "ticket".
For a fixed list of values from {Work Item].System_State, I can send the results (days in Assigned) to the column named (Assigned) for each status for each event in the [Work Item History], and then sum them for each ticket as:
Ticket ID      New          Assigned       InDev       etc
1230001        2                  0                 0          ...
1230001        0                  1                 2          ....      
SUM            2                    1                2         ....            
However, I have many different Projects, each of which use their own Status names.
I don't want to duplicate the same basic report, if I can avoid it.
How can I name and generate this data for the unique Status list for each Project?
Simplest analog is:  name = First(Fields!Status.Value, "TFSdb")
and allows value for a column name (category) as: =IIF(Fields!Status.Value = First(Fields!Status.Value, "TFSdb"), Fields!Days.Value, 0)
However this fails beause:
1. It only delivers the FIRST status value, and,
2. I cannot SUM an expression which is itself an aggregate (using First).

RRapport,
Is this still an issue?
