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.). </div><span class="HOEnZb"><font color="#888888"><div><br></div><div>- Aashish </div></font></span></div><span class=""><br><br clear="all"><div><br></div>-- <br><div><div dir="ltr"><font face="trebuchet ms, sans-serif"><i>| Aashish Chaudhary <br>| Technical Leader <br>| Kitware Inc. <br></i></font><div><i><font face="trebuchet ms, sans-serif">| </font><a href="http://www.kitware.com/company/team/chaudhary.html" target="_blank">http://www.kitware.com/company/team/chaudhary.html</a></i></div></div></div>
