[otrs] sort order of the QueueView

When I view My Queues, the order of the messages shown is the "Age" of the ticket. I'd like to change the sort order to be the message arrival time, not the time of the creation of the ticket's very first message (which is what I understand to be the "Age" of the ticket). I've looked through the mailing list archive, and searched the Defaults.pm file, but no success. Is the sort order I'm suggesting possible w/ OTRS? thanks. -- Alain M. Gaudrault, Reqwireless Inc.
