Add an option to CC people who are not users on leantesting in email

Adding an option to CC people who are not project members in leantesting through e-mail would be amazing. I have people in my organization that are not part of the QA team and I wouldn't want them to have an access to the bugs system, but I do want to keep them updated about the bug's status. Is it possible to CC people who are not internal users and keep them in the loop about updates?
