Refresh Message - Moving Dotted Circle

On slow connections to the internet, when a user selects a filter it takes time to refresh the various tiles in a report. But the icon of refresh ie the dotted moving circle which comes on the upper left hand side, is not very noticeable. Plus this is for each tile separately. one does not come to know whether the full report has got refreshed, and one has to keep seeing all the tiles to check if the moving cirlces have disappeared to ensure that the full report has been refreshed. Instead of this, PowerBI should show a bold message box right in the middle of the report/dashboard indicating that the refresh work is in progress, and when all the tiles are refreshed the message box should go off on its own.
