Need fully-qualified Activity code on report

Using P6 R8.2.

     I've written a report that reports time-phased resource assignments (budgeted hours across days....) Works fine, but for one of the columns I am displaying. It's an activity code. The code is hierarchical:

WR

     WR.10

     WR.20

     WR.30

EX

     EX.10

     EX.20

RPT

     RPT.10

     RPT.20

etc.

When I include that Activity code as one column of the report, it only shows the numbers (10, 20, etc.) and not the expanded hierarchy, As a result, WR.10 and EX.10 and RPT.10 have the same value. This is not what I need. I need the whole hierarchy in the column. Any ideas?
