Would also like to see this. Ideally with and option to pin it in both parent and child.
Use case:
Category = Gitlab
SubCategory = Announcements
Topic = Planned Downtime
Planned Downtime is an announcement. However, Announcements are opt-in, meaning not all users will see them. Consequently we also want it to be pinned in the parent Category.
Current work around is to pin it in the Parent for highest visibility, but that’s confusing for users who look for such information(correctly) in announcements.
