Assign organization_id & permissions using JWT

Hello I am using the latest version of Grafana Open Source.

I am wondering if I could use the JWT to, besides creating a user, assign it an organization Id on creation.

At the moment it looks like I can only assign it a role (Admin/Editor/Viewer) but it would have by default access to any dashboard.

Is there a way to create users through JWT with a defined organization and permissions?
