Ability to give access to guests to one page at a time only and not the whole space

Hi,

So this new "guest" feature is quite nice but it would be better to be able to give guests access to single pages at a time rather than the whole space.

Infact, I want some external users to access a page in a specific page.

But the way Confluence permission work is that I actually need to restrict all other pages that I do not want my guests to see.

That would be nice to have additive permissions on confluence space and not restrictive ones.
