Base filters on charts and list reports

App Builders now have an option to set a 'Base’ or default filter on any report (charts or list reports).  These Base Filters are applied before any user filters are applied and cannot be cleared by the user.  This is useful if reports are created to show (for example) only ‘Status Red Risks’ on a Risk Register.  This capability also allows the creation of content rich dashboards where charts can represent different data sets for the same app, such as sales charts for regions.
