Is it possible to duplicate a hierarchy in the Scene Outliner?

Hi Guys,

I have this type of structure:

18937-screen+shot+2014-10-25+at+8.10.38+pm.png

I want to be able to duplicate “Splashdown” in the outliner and have the new object contain all the children of the old object except those children have also been duplicated. Is this possible?

Tommy.
