Thanks for clarification. Yes, this is not currently supported (I am not
aware and we don't handle this in the mapper). This is a interesting use
case. I will add it to the feature request and will get back to you. Just
curious, what would be a real world example use-case you have for this
feature? Can you share bit more domain information (medical / scientific
etc.).
