Dashboard prompts to control all widgets

I have a dashboard for my work with this week, past due, and all tasks.  Rather than duplicate this view to manage everyone on my team into 8 different dashboards, could there be a prompt driven parameter to select users and see their activity within each of the widgets.  I think the only way to do that today is to duplicate my dashboard 8 times and change the user on each.   This could be a problem with larger teams and if I want to modify any of the widgets, I'd have to do that 8 different times.  

Thank you.
