Copy All Agents When Responding To A Ticket

Copy All Agents When Responding To A Ticket

Hello,
We run a very small help desk with very low traffic so we have some days where agents do not log in.  It is possible via a rule or macro (or something else?) to automatically copy an agent's response to a customer to all other agents during sending?   Currently, our agents have to manually type the email addresses of other agents in the CC or BCC field to keep them in copy.

Any help or pointers would be appreciated.

Thanks,
Keith
