Creating a Category Hierarchy in MediaWiki

Background:

I work with great collaboration, which centralizes a lot of documentation in the wiki. I am getting acquainted with wiki markup and can create simple pages with links, etc.

One of the main drawbacks of my collaboration wiki (based on the mediawiki architecture) is that there is very little organization or cross-connection.

I am trying to introduce a hierarchical structure of categories in a wiki, so that the pages are divided into categories, providing a means for linking information.

I know that I can add the [[Category: THISCATEGORY]] tag to any page source, and a page of a special category is automatically created that organizes other pages with this category. The main advantage of this page linking method is that you get access to linked pages for free (as long as they are marked), without requiring a direct cross-link between pages explicitly.

Question:

I am wondering if there is an effective way to create a root node category that, instead of linking to other pages, links to all categories? This would allow the wiki to be stitched together effectively without major repairs and would require the page author to provide some general category tags for any additional pages that they could add.
