I have an interface IFoo:

public interface IFoo
{
    int Id { get; set; }
}

And then a concrete implementation:

public class Bar : IFoo
{
    public int Id { get; set; }
    public string A { get; set; }
}

public class Baz : IFoo
{
    public int Id { get; set; }
    public string B { get; set; }
}

I'd like to be able to map all IFoo but specifying their derived type instead:

Mapper.CreateMap<int, IFoo>().AfterMap((id, foo) => foo.Id = id);

And then map (without explicitly creating maps for Bar and Baz):

var bar = Mapper.Map<int, Bar>(123);
// bar.Id == 123

var baz = Mapper.Map<int, Baz>(456);
// baz.Id == 456

But this doesn't work in 1.1. I know I could specify all Bar and Baz but if there are 20 of these, I'd like to not have to manage them and rather just have what I did above for creating the map. Is this possible?
