Is this Possible?

My Requirement is to use a Web Analytic script that let me filter my multiple websites from a Single Dashboard, sure Piwik can do this, but, i want to filter my websites even basis, which sites getting maximum traffic from USA/UK so on.

As i observed, right now i can only Sort websites basis Visits , Pageviews , Unique visitors.

Is there any way, we can even sort websites basis other mertics like Geography etc?

Thanks All
