Ability to cc team members Advanced Mail

It would be extremely helpful to be able to cc or even bcc other members from our team in Advanced Mail messages sent through automation broadcasts.

I understand the "Notify" function's abilities and they are limited in our case. We run a leadership development program and send 60+ contacts an email containing a personalized file. We want to be able to cc one (or more) of our team members on each of those 60+ emails as they will all have different files embedded. 

I see there have been similar feature requests dating back to 2019, is it not possible to enable this feature? Seems like standard practice for a CRM to be able to cc someone.
