CMS Request: Controlling Item Visibility for Specific Logged-in Site Members

Collecting votes
Currently, it is not possible to control which collection items are visible to specific logged-in site members without the use of member roles

This feature would allow site owners and collaborators to choose which items each specific site member could view. As a result, when members log in to your site, they would only see items they're permitted to view.
