Ability to allow viewing a single page in a space without view permissions

The idea being: allowing a single page (agenda, about page) to be viewed without access to the rest of the space, without needing to change the view permissions for the specific space.

Use case would be along the lines of: agenda or about page for specific to a space (owned by a specific team for example), but without access to that space.

It's a hassle to always adjust permissions across all pages on a space for any new users/groups each time an account is created/change.

Possible to use anonymous access at the space level for a single page?
