Restrict access to labels in JSD customer knowledgebase

Currently when creating a knowledge base in the JSD customer portal, you can limit access to articles in a space by adding labels that can be searched by customers, as described here:

Limit the pages that will be suggested - In the Restrict to articles with label column, enter the labels that must be applied to pages in order for them to appear in the suggested page list. For example, you might want to only include pages with the label "purchasing" to appear when customers enter a "Request new software" request.

It would be helpful if users could restrict access to certain pages based on label, as well as including labels that can be searched.

Additionally, it would be useful if the restricted labels also applied to the general search option in the customer portal so that when users search prior to submitting a ticket, results can be further filtered.
