Multiple NOC pages for each client

Do you currently use custom properties?  For example, a property named client applied to each node?  Views and accounts can be filtered by properties.

Create limitations based on custom properties​

Example:  Create custom property on node named client.  Assign it 'Kuhn'.  Modify view and/ or account to show nodes that have node property 'client' set to 'Kuhn'.  Note that limitations at the account level will keep one from seeing things a page might show (if the page was more permissive than the account).
