Page-Level Privacy

I love the ability to set the entire KB to private or public, however, I would also love to have the option to make some pages public, though the rest of the site is private.

In my use case, I would like to create a second workspace with industry knowledge that users pay a small monthly subscription to access. In order to attract new customers, I'd like to have a few pages that are publicly available as "teasers", and I could add an option to sign up (my own links) to learn more.
