Wordpress/Wishlist Member and Infusionsoft Integration

We have a membership website that's running Wishlist Member on Wordpress platform and we're utilizing the built in Infusionsoft integration, however, Wishlist only passes the First Name and Email address to Infusionsoft after registration. We need all of the fields on the registration form to pass into our Infusionsoft account, check for duplicates, and apply a tag.
