How can I map only specific hubs in SignalR

I have two hubs in my application. For the one I need NTLM authentication, and IP based filtering for the other. For this to work I need to set HttpListener.AuthenticationSchemes to AuthenticationSchemes.Ntlm for the first, while it remains Anonymous for the other. This means that I can not have both hubs running on the same listener connection. I have my OwinMiddleware to handle the authentication, and I am trying to set up two different endpoints for these two hubs (two different ports).

My problem is that when I don't know how to tell SignalR to map only a specific hub to specific IAppBuilder, and not all hubs that it can find. Any idea?

Finally, I managed to solve this using custom IAddemblyLocator. I wrote an article about this: https://www.codeproject.com/Tips/1237940/One-Possible-Way-of-Selectively-Assigning-Hubs-to

The basic idea is this:

using (WebApp.Start("http://*:8080", (app) => {
     var resolver = new DefaultDependencyResolver();
     var locator = new SingleAssemblyLocator(typeof(MyFirstHub).Assembly);

     resolver.Register(typeof(IAssemblyLocator), () => locator);
     app.MapSignalR(new HubConfiguration { Resolver = resolver });
   }))
{
    Console.WriteLine("Server running on {0}", url);
    Console.ReadLine();
}

Where SingleAssemblyLocator.GetAssemblies() is returning only the assembly passed to the constructor. Of course, each WebApp can be configured as needed.
