Hi Matt yeah I am planning on adding some more controls to the scene browser to make assigning more objects to the same name to be easier, something like a pop out menu that will have a "Assign to this name" menu item on it that would help with that.

In the meantime there is a plug-in that can help with that right now - it will add a command called AssignName which pops up a dialog that has all the existing object names in it so that you can then double click one to assign to the selected objects.

See here about how to install it and set it up:
