What's the best way to initialize an MVC Controller with multiple parameters of the same type using Castle Windsor?

In my MVC application, I'm registering all of my controllers using reflection in the Application_Start handler. This basically creates all types that are used on any controller parameter and adds it to the container.

I now have a situation where I have multiple parameters on my controller that are of the same type. Here is a simple example of my problem:

public class ClassA : ICustomType
{ ... }

public class ClassB : ICustomType
{ ... }

public class CustomController : Controller
{
   public CustomController(ICustomType a, ICustomType b)
   { ... }
}

I know that I can define CustomController in my web.config file using the <components> group. However, I'm curious to know if there is a way that I could specify 'ClassA' as my first parameter and 'ClassB' as my second parameter outside of my web.config file??

container.Register(
   Component.For<ICustomType>().Named("a").ImplementedBy<ClassA>(),
   Component.For<ICustomType>().Named("b").ImplementedBy<Classb>()
);
