Navigation/drilldown between BW Queries in portal

Hi:

I am at a client who are using BW and Portal. They are trying to integrate a bunch of BW Queries in to Portal. Their idea is if user clicks on a query table cell value, he should be able to drilldown, and another query result should be displayed. I am able to bring the queries in to portal and show them as pages. But I am stuck how to navigate from one query display iview to another, with a click of a button or a cell content. I read about Javascript commands etc. I know about context menus. But they don't want to use context menus. It should be one click of a button since users are managers (!!!!! ?????).

Please help.
