Impmelenting Google Analytics + (case multisite)

Google Analytics +
How should we implement Google Analytics + on our multisite in order to achieve next scenario:
1) Google Analytics for an entire network on main blog dashboard
2) Google Analytics only for subsite on subsite’s dashboard

The problem now is that on subsite’s dashboard you can see the entire networks analytics. In our case the subsites are not related to each other and only the analytics data regarding that specific site is needed on it’s dashboard.

Thanks in advance!
