Hi Greg,
For you (and others) who might consider an outside the box solution if it saved you enough time in report and dashboard maintenance, I invite you to learn about our "https://www.atappstore.com/Docs/uberfilter/UberFilterSummary.png">UberFilter solution, which lets you choose a filter at the top of a dashboard and have it "ripple through" all of the reports on that dashboard.
This way, you build each report once, then add as many filters as needed -- even ones folks might build themselves -- but keep only ONE version of the report. That makes it MUCH less daunting to then add a column, change a sort, modify a chart, etc. when the time comes: rather than hunting down and repeating the same change(s) in dozens of reports, you simple change one, and done.
Regards,
Doug
