[otrs] Ticket locked notification

Hi, Is it possible to send a customer notification when a ticket gets locked? I need this to notify the customer that their ticket is now being handled by an engineer. If this is not possible, then make this a feature request. When the engineer locks the ticket, a message like this should be sent: "Your ticked is now in the hands of <name>. She or He will contact you when ...blah, blah, blah". The customer then automatically knows that their ticket is is human hands, and that they should expect some development in a short time. Customer feedback is very important. Or so I'm being told ;) Kind regards, Thomas Vådahl
