Dashboard with a dropdown to control widgets?

I am trying to create a dashboard with a few report widgets. Each has data for our customers. I would like to have a drop down at hte top to filter just one customer at a time. I know I can build separate dashboards, one for each customer, but I am dealing with people that are not tech fans and having one that does this would make my life a lot easier.

Is this possible? I havent found much info on it.
