Bulk User Import with SHA-512 + salt key + iterations

We’re trying to do a bulk import of users with passwords that were already hashed. The passwords were hashed using SHA-512 + a unique salt key and 200K iterations. I’ve found the documentation for the SHA-512 + the salt key, but no mention how to do iterations. Is there a way to do this with the bulk user upload?lass_tilted_right: First try searching for your answer.
