As for how, you can take a look at
Native Advanced Ads as it seems to be the one you're looking for based on your description. Do note that Native Ads Advanced are in beta that only a few publishers can access. You may contact your Account Manager (if applicable) or contact our
support team if you're looking to participate in the beta. You can also use
Native Express Ads, but this has fewer customization options.
