Is it possible to bulk import users with multiple identities/credentials?

We need to import users from multiple web apps into an Auth0 database, and there may be users that are present in both databases, using the same email and different passwords.

We already created two scripts, one for each app, to bulk import all the app users into a database, but is there a way to bulk import users with multiple credentials?

That way maybe we can just create one unified script and for the repeated users import them with multiple credentials/identities so that they can login with any of their current passwords in the universal login that both apps will share.

I didn’t find any identities field in these article on bulk importing users, but maybe I missed something:
