You can't use QB Billpay to pay multiple bills to one vendor . You can sign up for a Melio account with the feature and integrate it with QBO. Make sure to click "Notify vendor" if you want to let your vendors know the payment is on its way.

You can also get $100 cashback to pay the first bill. Make sure to click Get $100 cashback button to sign up.
