NoProperty with computed values

[Zeguym]

Hello,

Is there a way to compute custom values when writing CSV with no proterty column ? In my case user can add custom rows with computed value and i would like do somthing like that, based on NoProperty samples :

private sealed class TestWithNameMap : ClassMap<Test>
{
	public TestWithNameMap()
	{
		Map(m => m.Id);
		Map().Name("Constant").Constant(row => row.Id + row.Name);
		Map(m => m.Name);
	}
}

With row of type Test

Thanks for your help
