I've got a question about attribute pricing. A client has this and Dual Pricing installed. The product wholesale pricing works great as that field is in the products table. For the attribute pricing, the field (options_values_price_w) is in the products_attributes table.

I thought I'd try adding it to the configuration anyway. No good:
User Defined Products Fields:
products_price_w: TRUE
options_values_price_w: FALSE

Is there a way to export and then import attribute pricing? Or would that functionality need to be added first?
