I believe you can only do this if you use the "To Spreadsheet" from the "Import/Export Data" tab of 2010 and then keeping the same format use the "From Spreadsheet" located in the same place.
Other then that AutoCAD: Electrical, by my knowledge is great at generating reports; but the second you make a change you have to redo the report. This is not a bad thing since reports are easy to generate and fun it you get into "User Post". :o)
