Seller Fulfilled Prime to Epicor Manifest

Hello,
My organization would like to participate in Amazon’s Seller Fulfilled Prime. As of today we print shipping labels for UPS and FedEx through Epicor Manifest v 4.0.5. Amazon MWS api currently does not integrate with Epicor Manifest. Is there someone out there that has integrated Amazon Seller Fulfilled Prime with Epicor Manifest? If so how?

Thanks!
