Pre vs. Post Deduplication report that breaks down by client?

Does anyone have a modified version of the Pre vs. Post Duplication report that breaks it down (in tabular form) by client (and pulls the client list automatically)?

I know I can edit the report and put in a specifc client (or clients) but if multiple clients are selcted then it totalls them all together.  I need (for Management) a report that tells them "where did all the space go and why can't you reclaim it by just moving some backups off to tape?"...
