One of our agents did manually create a ticket on the helpdesk department because the customer did contact him directly over his personal email. The manually created ticket somehow didn't trigger the default blueprint and the agent did not become aware of this before replying to the customer through the ticket. Right now the ticket has 5 message threads in it but it isn't being controlled via the default blueprint.

Is there a way for us to put this ticket into the control of the blueprint without losing the message threads in it?
