eCommerce email notifications - customize TO: or CC: field

Hi, Is it possible at all to customize what address do I send the order notification/payment notification emails to? Some customers wants order notifications sent to main user email, but payment notification to their accounts dept. I got these emails addresses in custom table (tied to the given customer), but on the email template there is no To: field at all, and if I try to use macro in CC field, it complains about wrong format.
