With Prism, how can I introduce a cloud RegionManager into a service?

Question

I am developing a Prism application and contains TabControlthat contains several child areas. Therefore, I implemented a custom RegionBehavior according to the template described by Brian Lagunas in his PluralSight course, which was found at https://app.pluralsight.com/library/courses/prism-mastering-tabcontrol/ and introduced a custom RegionNavigationContentLoader also described in the above course to make sure that I get no exceptions and that I can have areas of the same name on several tabs of my TabControl.

For those who do not have access to PluralSight:

I implemented a behavior that tracks the Views collection, and when it changes, checks to see if the added view or its DataContext implements a specific interface. If this interface is detected, it sets the cloud RegionManager to a property of this interface, so all views that fall into the area with the region can be aware of their cloud RegionManager.

However, I also have some services that require a cloud RegionManager to navigate to a child region inside my TabControl.

Since I create this service in my container, it gets the global RegionManager, not the region with the region.

My questions:

• Are there any patterns or structures that allow RegionManagement cloud managers to be introduced into services?
