Secondary Billing Option

I have residential and business RING products at two different locations - therefore need a second monitor/video recordning account. Billing option only give me the choice to enter one credit card. You should allow for another billing option (credit card) so we dont have to keep track of when our accounts are up for auto-renewal and need to go in and switch from personal credit card to business credit card. The one billing option defeats the purpose of auto-renewal.
