Problem statement

Currently, Jira Service Desk Knowledge base only allows for a global level management of categories. Articles that are related to a main subject either get lost inside the bigger category or end up with their own category thrown in.

Suggested solution

As an admin of Jira Service Desk, I would like to be able to create subcategories for already existing categories in the Knowledge Base.
For example:
Category: Cars
Subcategories: Engines, Tires, Windshields

More often than not, categories do have more detailed information within them that the current tooling does not allow for better management.
The example above allows me to have a category for cars as a whole and then, dedicate subcategories for car related articles in more detail.
