Is there a way to limit the population that a user/Line Manager can assign journeys to?

Summary:

A line manager should ONLY be able to assign a journey to their direct reports.

The role set-up limits a Line Managers access to their hierarchy/management chain; yet when assigning journeys they can assign to anyone in the Organisation which isn't behaviour I'd expect.

I raised a service request and they confirmed this is expected behaviour. Has anyone else had this issue raised when implementing journeys?

We have over 25, some are auto triggered, but many require manual assignment.
