kitchen faucet fillers??

My question is, I purchaced a new faucet that is designed for a one hole install, however my kitchen sink is a three hole configuration. I love the faucet so I would really like to keep it. Do they make fillers that would fit over the open holes left behind by the new faucet? The sink is a cast iron sink. If such a thing is made where could I find one to match the color of the sink, which is white?
Thanks

Yes they do make hole covers in various finishes. They also make soap dispensers, which are a nice touch.

Thanks! Found them at my local plumbing supply store.
