importing a file with numbering

Hi all, Is there a function that numbering the records automatically when I import a file using the excel import? When I try Import a file, all attributes but type:AutoNumber attribute has successfully imported. I want this attribute below to have type of Autonumber, and set empty for the excel column so that the Mendix can number the records.   I would really appreciate if you help me how I can should rewrite the excelImporter module if I have to. Thank  you in advance, Regards Yuki

Autonumbers are created by Mendix when the object is created in the database. There should be no need for an excel column
