Autofac register and resolve with Names

I'm trying to register objects by their names, and later on take them in another type's ctor as parameters, during registration.

Hope my example will be clear enough, here it is:

public class Obj : IObj
{
    public class Obj(string name)
}

I register the following objects like this :


public void RegisterMyObj(string name)
{
    // Keyed with the object name
    builder.Register<Obj>().Named<IObj>(name).WithParameter(name).SingleInstance();
}

public class ObjectsHolder : IObjectsHolder
{
    public ObjectsHolder (List<IObj> objsToHold))
}

// I want to register my ObjectsHolder in the following way:
for example, this is how I want to call it from my code: 
    RegisterObjectsHolder(string Obj1Name, string Obj2Name)

public void RegisterObjectsHolder(params string[] objectsNames)
{
    builder.Register<IObjectsHolder>().WithParameters(// Here comes the magic code which I can't figure out. 
                                                      // I want objects holder to be registered with the Obj instances whose names were passed to this method, 
                                                      // is there a way to do this?)
                                                      )
}   

I'm not strict about the ways the registrations will look.. If you know of a way to accomplish this using different methods, that will also do.

Thanks in advance!
