Is there a way to update the structure of the post entity, but only when displaying a thread and not when posting to the thread. The columns I'm adding are needed when you view a post, but I don't want them added to the structure when trying to save a new post as these columns don't actually exist in the db table(s) for posts. I'm using a code event listener right now that listens to
event_structurewith the event hint
XF\Entity\Post, but that fires on both page view and when making a new post.
