How to grant course creation permissions without it needing to be requested?

It seems like the normal flow is that course creators are granted staff permissions on some existing course, then they log in and request course creation permissions. Is there a way to just grant them course creation permissions without adding them to an existing course?

@oedx They should be able to create an account without being invited to a course. The necessary preliminary step is to have them creating an account, before being able to grant them course creation rights. But the user accounts are actually shared between Studio and the LMS, so the ability to create an account for Studio should be possible without staff access on any course.

Agree with Xavier @antoviaque it is possible to create an account without being invited to a course. Course creation rights needs staff access though.

Where is the UI for granting course creation rights? (e.g. I can’t seem to add new people who haven’t requested it already from Django’s course creators section @ https://studio.bla.com/admin/course_creators/coursecreator/ )
