GS Membership with multiple emails or addresses?

My girlfriend and I have a camper and membership together, although all of her information is "on file" with a separate address... (long story) Is there a way to have multiple names or emails? I ordered online from Camping World, used her / "our" number for discounts and my address for a ship to and bill to (where the camper is garaged and we both live) and a week or so later we were in the store and it seems ALL of the information on the account switched over to my name and email...

Is there an option for primary / secondary or anything?
