I have the following container which describes some User. It has both factories and singletons specific for this user.
It depends on a ClientSession object which can be injected from some other Root container:

class UserContainer(containers.DeclarativeContainer): client_session = providers.Dependency(instance_of=ClientSession) some_service = providers.Singleton( SomeService, client_session=client_session, ) 

Currently I simply override it when creating UserContainer:

 user_container = UserContainer( client_session=providers.Object(client_session), ) 

Is there a way I can provide a Root container instance itself to the UserContaner instance instead of providing the service itself? Note I can't mix them as singletons in UserContainer are scoped
