Sort Unassigned by User Name

We have a fair number of customers who will double, triple, quadruple text or email, and it would be very helpful to us to be able to sort the Unassigned Inbox view alphabetically (or “Waiting since” chronologically first, “User [name]” alphabetical second), to allow us to see these extra instances at a glance and avoid the risk of two CSRs addressing the same customer concern because the two messages were assigned separately.
