Setting up a signature rule for a sales team

Hello

We have a sales team comprised of an outside sales and inside sales person. I need to set up a signature rule where the email would come from the CAteam@company.com. I have the dynamic content set up for the email content but how do I set it up so the email sender appears as the team? Do I need to make the team name/address as separate users in Eloqua?

Thanks in advance!
