not sure as I don't know what the over arching purpose of the report is, but to drill into something from a summary, that same something must exist in the rest of the report. Meaning you have to have grouping that allows you to display the details of what was summarized. you have to architect the report to support the drill into unless you want to make sub reports for all the "drill down" options.
When you create a group and insert a summary you can insert a report header graph using the 'Group" option in the Data tab.
this mimics the same thing as drilling into a group (clicking on the group header) but puts the "drill links" into the chart.
I would start with what the end game for the report is and work backwards from that.
