Continuation of discussion that happened in #tagging on discord recently.
We have many posts where someone wears mentioned outfit tagged as Hibiki (Blue Archive) (Cosplay).
The problem here is that this kind of outfit is not worn only by her (Kotori (Cheerleader) (Blue Archive)), comes in different color variations, and many tagged as such posts do not even show the exact same blue variant that Hibiki wears (post #6194451, post #6166081).
The proposed solution was to make a new gentag Millennium Cheerleader Outfit (Blue Archive) and retag all Hibiki (Blue Archive) (Cosplay) posts.
Hibiki (Blue Archive) (Cosplay) should be used only for posts showing distinct to Hibiki's outfit features - either her original outfit, or at least her blue-tinted safety goggles and blue-colored cheerleader outfit.
Attached BUR will remove hibiki_(blue_archive) and hibiki_(blue_archive)_(cosplay) from all posts tagged hibiki_(blue_archive)_(cosplay) and add millennium_cheerleader_outfit_(blue_archive) instead. The new tag will also be added to all Hibiki (Cheerleader) (Blue Archive) and Kotori (Cheerleader) (Blue Archive) posts as well.
Few posts may be tagged incorrectly as a result, but since this tag is not that big yet (283 posts at the moment), it would be possible to just handpick them beforehand and retag correctly later. As for kotori_(blue_archive)_(cosplay), it has just 7 posts so far, and can be retagged completely manually.
