Personalize Lead Database Dashboard

Does anyone know if it is possible to personalize the criteria for Marketable Leads from the default*? Also is it possible to change the chart on the right to something other than Top Source?

*Marketable Leads: The number of all-time leads for the workspace, minus the following: leads without an email address, leads whose email has hard bounced, leads that are blacklisted, leads that have unsubscribed, leads currently set to Marketing Suspended.
