Define CC mail in workflow

Currently when creating a mail alert inside a workflow, it's impossible to define a "CC" mail address. Several recipients can be added (eg: candidate+candidate owner) but the candidate owner can't see that the mail was also sent to the candidate itself. This is highly problematic to follow and control all automatic mails sent to the candidate! Could you please add a CC option ? Furthermore, the field "Additional Recipients" can not but used as it accepts only fixed mail address. Regards, Quentin
