Hi Sameh Elsharkawy - I hope I am not missing anything but I think this is exactly what the option "Add New Translation Unit" does on this dialog box. It says "If target segments differ, add new translation unit" and this would mean that you can keep two or more translations. Have you tried this and would you agree? We designed the import feature to accommodate this important request as it often happens that you would like to keep several translations for the same source (and then the multiple translation penalty kicks in so you can choose which to pick, and PerfectMatch keeps the sequence in a document so you can then use PerfectMatch to avoid the multiple translation penalty). Thanks, Daniel
