Safari Cookies: Where is "Allow from websites I visit"

When you read Apple's support page they talk about being able to setup more granular options for managing cookies. I can't see none on the Privacy tab, as you can see below:

Indeed where are the options:

• Always block:
• Allow from current website only
• Allow from websites I visit
• Always allow

Of course, I'm on High Sierra with the latest version of Safari 11.1

Any idea
