When creating a new tenant an option to create same set of users from existing tenants

Option to create new tenant with same set of users as one of the existing tenants.

When creating a new tenant it would be useful to have an option to create the tenant with set of users selected from existing tenants.

I don’t follow the use case for this. You can map an IDM at the tenant level and grant access the same as another tenant. That said, what is the purpose of users utilizing 2 tenants?
