The addition of an action code called "#merge" at the top of ANY email addressed or cc'd to the helpdesk and then the option being the Ticket ID. e.g. #merge  This action code would then merge the email message into the messages of the ticketID in the option. This ability gives you the power to have one on one conversations with vendors and other people outside of your organization that you do not necessarily want to be part of the ticket communications, but the information within those emails pertains to the ticket.
I want an option to add CCs to the ticket besides the requestor (#user).
