As a workaround to this, typically in GP, we post a placeholder, delete it, and then post the complete check in that order. That makes sure the user gets an alert for the complete check but also lets us use placeholders for organization. You could try that for QCing too
For my stuff that works but I can't rely on others when they're QCing or GPing my content to do so. Also for stuff like Stour getting a notif when the post is updated would be really useful :)
