Can we trace categories changes in Audit Log

Summary: Tracing categories changes in the Audit Log

Content (required): As we all know, we can trace the incident transactions through the Audit log. But one of my client requirements is, they also want to trace the categories changes in the audit log like when and what categories changes done by an agent?

Is there any table where we can track the category changes in the audit log or any other possible way through a custom report?
