Sheet Summary Report - Want to edit fields within report

I created a Sheet Summary Report, and have found that the fields within the report are not editable, unlike a Row Report.  In a Row Report, I can click into the cell directly within the report and update it.  On my Sheet Summary Report, the cells in report are locked down and uneditable. 

Am I missing something in order to be able to do this?  Or should I submit an enhancement request for this functionality?  If it's not current functionality, is there reasoning behind why a Row Report will allow it but a Sheet Summary report will not?  I want to use a Sheet Summary Report as a Current User status report and it would save so much time to update overall project statuses from within the report instead of going to each individual report.
