Apologies for not understanding the question.
I think it will be a custom work. If you are comfortable enough to code then you can do it yourself or else you can take help of any experienced person.
Here’s an idea to create new taxonomies when a post is created for CPT :
You can use this action https://developer.www.ads-software.com/reference/hooks/save_post_post-post_type/, write your own function on this hook in which you can check if the post is being created first time (not an update) then write the code for registering taxonomies.
I hope this will help you.
Kind Regards
