How do I get a resource in use report?

Background:
If you try and change a plans resources and a user is using more than they should of a resource you will get an error like this:
Error : 70100510 : Update failed; some Resources are in use.
Right under that error is a link for that says "show/hide report"
This report gives a list of resources that are overused in the plan you just tried to change.

What I would like to do is be able to get that report for all plans under a specific reseller or all resellers if at any level. Is this possible, if not HC can it be added in?
