Average Time in status gadget only applys to resolved issues

The average time in status charting gadget only applies to resolved tickets. So you can only get reports on how long a ticket or tickets have been in a status if they are resolved.

We would really like to be able to track time in status for all currently open and resolved issues issues and display that as a series-based graph. Is this something that could be added to the Time Status Gadget or a further gadget provided that would do this?
