Custom header for specific pages (with variables)

When will it be possible to change the header section of a page with some data from the app? I understand this was a planned feature this month. But I don’t see it Did I miss something?

The use case here is to create a page that can be shared on Facebook or social media in general, with specific meta tags in the header. Right now, it is only possible to change the header of ALL pages. This isn’t helpful when each page has a different content (different title, different featured image…).

I believe SEO settings are currently under a rework, however, I’m not sure if this includes a pages head tags.

I’m going to move this to the suggestion box for the time being because it seems more appropriate.
