[otrs] Multiple Closed states

Hi I am sure you knowledgable users of OTRS will have a quick answer to this. We would like to have various Queues, such as Software Support, Hardware Support, Finance etc. We would then like to have a couple of ways where the Ticket appears closed (and is notified) to the customer Default would be if the ticket is closed, is chargeable and is put into the Finance Queue where it is finally closed when an invoice is raised. The other way is if there is no charge after a phone call or whatever. Either way, by closing it or moving it to Finance, we'd like the customer to get a closed notification. Is this possible? Thanks Neil
