Registry vendors contracted with Weddingwire to show up on website

Hello! I'm wondering if anyone knows which registries will be able to sync directly on your Weddingwire wedding website. We have 2 registries and only the one from Target is able to show up directly on our website. This wasn't a problem we though, but literally no guest has actually clicked and directed themselves to our registry at BBB. Are there other registries that will show up on our website? We might just make another registry that will actually work with the website. Thanks for any help!
