Grouping objects together

 From:  mickelsen
I think this is a topic that has been discussed before, but I'm going to ask now to see if there have been any changes.

Is there a way to group objects together so that they can be manipulated as a single entity? I mean that I would like to select them all with a single click, move them all together, copy them, etc. This is easy to do in Rhino. Does MoI have anything similiar now?
