How to configure NServiceBus with two RavenDB IDocumentStores?

In NSB 5, how do I correctly configure NSB with autofac container with one IDocumentStore for NSB data and a separate IDocumentStore for application data? I've pasted the relevant part of EndpointConfig below:

            // Raven DataStore for Freight system
        var appDataStore = new DocumentStore { 
            ConnectionStringName = "RavenDB",
            DefaultDatabase = "ApplicationData"
        };
        appDataStore .Initialize();

        // Raven DataStore for NServiceBus
        var nsbDataStore = new DocumentStore
        {
            ConnectionStringName = "NServiceBus.Persistence",
            DefaultDatabase = "BookingProcessing"
        };
        nsbDataStore.Initialize();

        // Set up and build AutoFac container
        var builder = new ContainerBuilder();
        builder.RegisterInstance<DocumentStore>(appDataStore ).As<IDocumentStore>().SingleInstance();
        var container = builder.Build();

        // Set up NServiceBus
        configuration.UseContainer<AutofacBuilder>(customizations => customizations.ExistingLifetimeScope(container));
        configuration.UsePersistence<RavenDBPersistence>().SetDefaultDocumentStore(nsbDataStore);

I know this isn't working since I had problems storing sagas in another question. The SagaPersister tried to persist saga in appDataStore, but the Timeout Messages was persisted in nsbDataStore.

This is a sample for 4.x using unit of work, If you use

will this help?
