Auto Update of ESRI Featured Content - Basic Viewer

Question

I have noticed that when you create a web map with a feature service set to refresh every minute, that the ESRI Basic Viewer will pick up the new/deleted features using that web application.

But, what if the web map behind that web application added a new layer and saved the map?  The basic viewer has no idea the map changed, until you refresh the web browser of the ESRI Basic Viewer.

Is there a way to notify the viewer that the map has changed and to tell the viewer to update itself?  This is classic observer pattern, but can I make it work using the ESRI Basic viewer?

No, I don't think so.
