NX11 in Teamcenter Integration - NX expect standard dataset MSExcel

Hello,

here all datasets in Teamcenter are named with a prefix e.g. RB6_MSExcel (RB6_Item, RB6_ItemID, ...).
If I will import values of an excel file from Teamcenter (e.g. for expressions) NX did not show the RB6_MSExcel because NX expects a dataset MSExcel (without our special prefix).
Is there a possibility to map it, or a preference in Teamcenter to solve it?

Thanks
