Space Category in Confluence

Problem

We have categories in Confluence, and any label that a user adds to the space is included in this category. Therefore, it is challenging to obtain the spaces that belong to a specific category.

Why This Is Important

In order to bill, we often need to know which spaces belong to a specific department or region.
Obtaining the list of space labels from the database and determining if the label for the department or region is present in the list is an extremely time-consuming job.

Suggested Solution/Feature Request

As in Jira, we so require a single value picker category field in Confluence to classify the available spaces. We would also like to have the ability to export the Confluence space list with categories.
