When we import a DGN file that contains multiple insertions of the same cell, each insertion becomes a differently named BLOCK after the import.
In some cases, there are hundreds of insertions of a particular cell/block which means in the DWG, instead of having hundreds of insertions of a single block definition, we end up with hundreds of block definitions, each inserted once.
Here is a Microstation dialog showing 2 of the same named cells (there are about 20 of these cells inserted in the DGN)

Here is the result (list of blocks) after DGNIMPORT. Each one of the "Check?" blocks are the same.

If we open the DGN in Microstation and then save as a DWG, the result is better, meaning that not all of the cells are treated this way, but it still does the same thing to *some* of them. There doesn't seem to be any rhyme or reason for this.
The end user wants to edit this block one time and have all the insertions update, but that's impossible of course when this happens.
Any thoughts?
