Ticket-Specific Workflow for Teammate or Customer being unresponsive

It would be helpful to have workflow for tickets that would be initiated if there was teammate or customer (could be two separate options) has been unresponsive for a specified time frame, which would indicate that the ticket should be considered done and can be updated to the appropriate status and closed. You could also have variables such as whether the conversation has to be closed for the flow to apply. This allows the more automated handling of tickets for teams, keeping queues manageable.
