Help with animal tags

[Diawol3]

People, help with one question, which I will not find the answer to. I want to split the creature into normal tags, in the style of dogs, dragons, horses, etc. But you can do this only manually. Not only that, all these animations are initially scattered across different tags (there is not even an animal tag), so they still need to be manually added to some unnecessary tag (for example custom). Is there a mod or program that would not allow for 2 days, but for an hour or two to do so ... Thank you in advance and apologize for broken English, machine translation
