Alternative to mega-threads

I'm not 100% sure if this is the right community for my question. Should that be the case, I want to apologize.

Alternative to mega-threads: Could this feature be implemented by a Lemmy instance?

Basically, my idea is to allow community mods to quarantine posts into groups called super-threads. These super-threads would show up in the community appearing like regular post. But when you open such a super-thread, you would see an overview over all the posts quarantined to this super-thread. It would look similar to a community. Quarantined posts could still be found by a search but they wouldn't show up in the community overview or the general feed. Only the super-threads themselves would show up there. That way, mods could stop a single topic from overwhelming a community by quarantining all related posts to one super-thread. Thereby, super-threads could replace existing mega-threads while maintaining the forum-like form of Lemmy.
