At this point in time, there is no option available to configure the dashboard view on the Home tab.
It will show you the sum of envelopes falling into the different categories for the envelopes in your account for the last 6 months. You cannot change anything on this dashboard, which means no filter can be applied to distinguish between employee and client documents. Also you cannot duplicate the dashboard or change the filter to a different time span.
"Select as Best" below if you find my answer is a valid solution to your issue and mark it as resolved.
