Bulk Edit Shared Report Fields in a Dashboard

[#1]

Just how you can bulk edit shared fields in a task, user, project, etc. report, I want this ability for shared fields within reports in a dashboard, or selected reports within a dashboard that have the same field to edit. A lot of our dashboards have reports that share common filters (like a date range, category ID, etc) and when we need to modify the dashboard, I have to go into each report within the dashboard to change the same thing. It would save me SO MUCH time to be able to do this in bulk in a dashboard.
