Passing variables to ReportSmith detail reports

Hi,
     Does anyone know of a way of passing variable values to a ReportSmith
**detail** report from Delphi. Only the master report seems to see the
values passed in the InitialValues property. The 'get from file' option in
ReportSmith is the closest I can get, but prompts the user to confirm the
value.
  Thanks
