Add groupmail to CC for a project

Hi,

I am wondering how we can add a groupmail address to CC for a certain project so the people in the groupmail address can follow up on the project.

I know there is the option to add a Project coordinator besides a Project manager, but what if we want to send this to a groupmail? (Just making an account for a groupmail would use up an XTRF license.)

Adding the mail address to CC in the templates could work, but then all the mails for all projects would be forwarded. I only want to forward the mails in case of emergency when the PM in charge is out of the office.

Thank you in advance.

Wim
