Would it be possible to modify the headings of the report result columns with filters, which could be built and populated on the unique items in the entire report? So for example, the report is generating, and as it is generated, it tracks unique entries for each column, and then the header is created as a dropdown, populated with those unique entries. Then, after the report is run, the user could, if desired, select one or more items in a column dropdown that would update the results from those selections?
