Any ability to add custom filters to MPI?

MPI seems interesting. It certainly addresses a good portion of program performance in relation to the funnel.

Is there anyway to add custom filters to the MPI dashboard? For example, we have Distributors/Resellers listed as contact roles on our opportunities. These contacts greatly skew our pipeline/revenue figures because they've had successful marketing interactions, but we wouldn't want them included in our figures. Could we add a "Opportunity contact role does not equal" filter to the dashboard?
