Re-certification in IBM Security Identity Manager 6.0 no Person Types

I just find it a little annoying that when creating re-certifications in SIM 6, you can choose persons of type Person or BP Person, or you can choose all Persons, but if you had any custom SIM person classes defined the tool gives you no way to select your own custom Person type.  Like the developers got 3/4 of the way developing this feature and said, "Oh, good enough".
