Any addon for showing locations of Rare Spawns?

Hey there!I've put up a personal goal in classic for myself which is to kill all rare spawns. I'd love if there was an addon kind of like Questie that shows the locations of rare spawns. Doesn't need to actively search for any or anything like that, just show me where they should spawn on the map.Thank you for any help!​Edit: I know I can google the locations but since there are hundreds and hundreds of rare mobs, I'd love it if I could just check the map in each zone I'm in to quickly gauge which areas I could do a little check on while questing.
