Flatten Domain Class To ViewModel When Source Is Complex - mapping

Question

I am using ValueInjecter to map domain classes to my view models. My domain classes are complex. To borrow an example from this question:
public class Person
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public Address Address { get; set; }
}
public class Address
{
public int Id { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
}
// VIEW MODEL
public class PersonViewModel
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int PersonId { get; set; }
public int AddressId { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
}
I have looked at FlatLoopInjection, but it expects the view model classes to be prefixed with nested domain model type like so:
public class PersonViewModel
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Id { get; set; }
public int AddressId { get; set; }
public string AddressCity { get; set; }
public string AddressState { get; set; }
public string AddressZip { get; set; }
}
The OP in the linked question altered his view models to match the convention expected by FlatLoopInjection. I don't want to do that.
How can I map my domain model to the original unprefixed view model? I suspect that I need to override FlatLoopInjection to remove the prefix, but I am not sure where to do this. I have looked at the source for FlatLoopInjection but I am unsure if I need to alter the Match method or the SetValue method.

you don't need flattening, add the map first:
Mapper.AddMap<Person, PersonViewModel>(src =>
{
var res = new PersonViewModel();
res.InjectFrom(src); // maps properties with same name and type
res.InjectFrom(src.Address);
return res;
});
and after that you can call:
var vm = Mapper.Map<PersonViewModel>(person);
