Ability to link single Confluence page as Knowledge Base rather than entire space

Problem

Currently in Service Desk it's possible to link an entire Confluence Space to use as knowledge base article. No option to link a single page.

Other things to consider

The Anonymous access permissions are usually tied to the space itself, and then you can restrict anonymous access from individual pages. So you would need to be able to somehow ONLY enable anonymous access for a single page without affecting the rest of the space.

Desired resolution.

• the option to link a single page
• the option to allow anonymous access to a single page in Confluence.
