Closed Ticket Exclusion

Crewhu includes tickets with statuses that are technically closed but do not send surveys to clients.  We use "Closed - Silent" status to close a ticket that's a duplicate or in other scenarios where we don't want to send a survey (or any email) to the contact on the ticket.  This messes up the CNV calculation that Crewhu reports because all of those tickets are included.  The work-around to move those tickets to another board is not good for other business reasons, so we'd like the ability to exclude a specific status from what Crewhu considers "closed tickets."
