Frequently the layout of a dashboard needs to be replicated so each item uses appropriately filtered views/data.
For example, I may have identically laid out dashboards for:
-All Company Data
-My Company Data
-Territory 1 data
-Territory 2 data
-etc.

It would be helpful to have a filter on the dashboard that allows the user to change the data represented. The current options of "Creating one dashboard for each dataset" or "Having users select a different view for each item on the dashboard" are unwieldy.
