I think it would be very useful to have a separate grouping of views which lists items appearing on the same dashboard view. This could be similar to the current “Primary Views”, “Ref Views” groupings. You would have a pane called “Dashboard Views”, then have the dashboard name, and then subpanels for each included view.
Alternatively, you could add a “go to view” type action next to the “Delete” button in the current ‘View Entries’ panel. This would really help with navigating through the subpanels, and reduce the time spent scrolling through lists to make modifications.
