Auto payments - 2 Tesla's same account - I have 2 Teslas's in my account. I can't use a different bank account for auto payments.

[Lauramye]

I have 2 Tesla's in my account. I set up both for Auto payment with different bank accounts. If I switch one payment to XYZ bank the other automatically switches as well. Do I need to remove one of the cars from my account and set it up in it's own account? I can't get ahold of anyone (big surprise) and I need each car to have the auto payment from a different bank account. HELP!
