If you check “I’m an advanced user” in the settings, then hit the “More” button in the dropdown a few times it’ll show the more advanced interface that lets you choose which third party domains to allow. It doesn’t work quite the same since it blocks both content and scripts per site, but I find it good enough for my usage.
edit: You can technically block just scripts per 3rd party site, but it involves manually editing the content type for your rules in the settings. It’s not part of the main interface, so I never bother using it.
