Unique payment method for every facebook ad campaign

Hey everyone,

I've been doing some research and haven't found anything that seems good enough. Currently talking with several people about their services but thought about asking everyone here:

How do you go about have a unique payment method (e.g. CC or PayPal) linked to your ad campaign on Facebook while being able to quickly have insight into the funds on the card (so that you can fund it more if need be)?

Any links, suggestions or just general information will be greatly appreciated.

Think you can only have one payment method per account. Don't think it's possible to have a unique payment method per campaign. Use a Paypal account or Credit card under your name!
