CE Sheet Index - Sheet names

Hi

I have a great deal of clients that over a vast period of time have created Sheets models with the name of the Paper size ie A1 Sheet.  This was great but now that we have sheet indexing, this is a right pain.  The Sheet index import tool will only show the sheet model names and not the dgn filename.  Thus, I have hundreds of indexed sheets all called A1 Sheet , A3 Sheet etc.  Next to useless.  

Thus when we add sheets to the index we need to be able to change the index name ie use the dgn filename.
