Data Import - Lookups

Hi, 

Is it possible to specify a different attribute (unique attribute from the source table) instead of Name in the Data Import templates for Lookup columns? 

For example, to update existing prices an import to Product Price table must be done. In the Data Import Template for Product Price table, there is a Product (Lookup) column. The name of the product goes in the Product column for bpmonline to identify the referenced product. Is it possible to use Product code instead of Product Name as there may be more than 1 product with the same name but the code is unique across the entire product catalog. 

Regards,

Hatim
