[AS] drill through to [RS] multiple values

[Nathan_F]

I am trying to find out if it is possible to pass multiple parameter values from an Analysis in [AS] to a Report Studio target.  I have a DMR package for the analysis and a relational package for the target Report Studio report.  The target has 3 parameters with the "in" option on the filter.  I have set up the drill through definition from my DMR package to the Report Studio target.  I have 2 of the parameters as single context items in the Analysis, with the 3rd as multiple values in the context.  When running the drill through, however, it only seems to pass the topmost value from the 3rd context item. 

Is it possible to pass multiple values this way?  If so, any advice on how to do so would be welcome.

Thank you
