When you have added ConcurrencyMode=Fixed once in your edmx file, then afterwards every time you update your model, before checkin in code (assuming you have some version control life TFS setup), compare with the latest version and merge changes accordingly. This way you dont have to update every single line manually. Not the best way, but better than doing it manually atleast.
