Drill through multiple values?

[gatorfe]

I have a report that summarizes sales figures for a specific time period with drill throughs set up for detail.  When I run the summarized report the user is able to choose multiple companies and a time range.  They can click on the total figures to see the detail behind the number that shows up on the first report.  Is it possible that the drill through pass two company values?  I can only get one to show up on the drill through detail report.  I have all my parameters set to "cmpy code in".  Thanks in advance for any suggestion.
