Drilling into Cycle Time for Portfolio Items

[V Scire]

I see there is a Dashboard Panel for Portfolio Item Cycle Time, but it looks like this can only be filtered by Program and Project. Is there any plan to add more filtering capabilities or additional x-axis options to the report, similar to what is present in the Workitem Cycle Time report? For example, the Workitem Cycle Time report also allows the user to use Class of Service for the x axis. 

Ideally, both the report and the dashboard panel would be able to be filtered in addition to changing the x axis - for example, filtering to expedite class of service and seeing the cycle time broken out along the x axis by workitem size.
