[Paraview] Where did vtkMultiGroupDataSet go?

[Mike Jackson]

Great. I have things generally working. I would like my users to use  
the "Extract Block" filter to extract certain portions of the  
dataset, but when I select that I see a list of blocks labeled "Block  
0, Block 1". What do I have to set in order to get something more  
"human understandable" in that list? Something like:
   Simulation Limits
   Dislocation Data


Thanks
