History of reports sent should include segments or reportlets used in the report

[#1]

We have a multitude of business users who create ad hoc reports and send copies to themselves via email, but the report archive does not include any information about the construction or parameters of the report, such as dashboard used, reportlets, time frame, segments, even the type of report generated.  This creates a tremendous volume of support time for our organization trying to help re-create reports our business users create and then want to recreate.
