I have to create over 1000 new groups (import via CSV)

I have also to create over > 1000 users. (import via CSV).

But every user has to be assigned to a specific group (every user has his own group).

When you add a user manually in OKTA than it is possible to assign this user to an existing group.

But on import of users via CSV is that not possible.

Now I have to assign each of the 1000 users manually to a specific group,

Hopefully someone knows how to automatically assign a user to a specific group.
