Option to Reset a Report Filter

I encourage my CSMs to take advantage of being able to filter the reports on their dashboards by themselves. They will use them to change the date range, or view different data from any individual report. The problem is that there doesn't seem to be a way to then reset these reports back to the way they were originally created. The CSMs don't always know what the original filters were and end up getting stuck with reports that don't give them as much information.

The filters seem to persist even with a page reset or after multiple days. It would be nice if there was a reset button on an individual graph like exists for a global filter.
