We at Anime&Manga get a lot of identification-request questions, which usually don't conform to a number of rules for posting these kinds of questions. And while the generic "unclear" close reason also applies, it would be neat to have a more specific close reason linking to the meta post with all the bullet points which should be filled out to make for a proper question.
But this will only make sense for questions tagged as identification-request. For all other questions this custom close reason would be irrelevant. Is there currently a way to make such a custom close reason to only show up if the post has a specific tag?
I'm sure many other SE sites would benefit from such a handy feature for very unique tags which don't work very well with generic close reasons.
