New Products with "Distributor" option

[Guest]

I'm wondering how I could add the option for a "distributor" when adding products to my catalog.

 

Currently, you can only include: Products Status: In Stock Out of Stock Date Available: Products Manufacturer: Products Name: Tax Class: Products Price (Net): Products Price (Gross): Products Description: Products Quantity: Products Model: Products Image:.......etc

 

How can I add "Distributor" to this?

 

Thanks to everyone who supports OScommerce!
