On Dashboards, you can hover over a Global filter, and the impacted reports are highlighted. It’s a bit subtle but it’s nice to have some indication that if you make a change, you know which reports were modified.
Would love a similar function on GS Home. Given some of the limitations on filters, you may just be slapping reports/widgets on home and users need to tweak them individually - but unless there’s some other callout there’s no immediate way to know if your report should have changed and didn’t, or shouldn’t have changed.
