You would need a 3rd-party Crystal report viewer for this. For a list of 3rd-party viewers, see: http://www.kenhamady.com/bookmarks.html
For a short video demonstration of how "in-place drill-down" works in one of these viewers, see:

Note: to make this work for your report, you would need to add some formulas to the report.
