Coping Dashboards as a new dashboard and only changing one metric.

I'm currently trying to create about 40-50 different dashboards for all the Entities of our company.  I want to show the exact same metrics in each box of the dashboard but the pages will change from dashboard to dashboard depending on the Entity.  We've created a custom traffic variable where these entities are being populated together so that is the only metric I would need to change from each dashboard.  Unfortunately I've been told that to create all of these dashboards I will have to go and create every single report for every single entity and individually assign them to each Entity Dashboard.

I think there should be an easy way to copy an existing dashboard over as a new one and change small things within the new dashboard created.
