#hikashop_order_product and field product_parent_id

Hi, first I want to thank for the help you gave me these days. I want to ask if you can add to #__hikashop_order_product - field product_parent_id. Why do I need that value? Because I will work mainly with variants created by other vendors (Hikamarket) I want to make a plug-in that shows which users have bought a product from there, making it easy to integrate with my social network. The code is ready but it works only for the main product but not for the variants (it allows me to retrieve only one ID of the variant, if I have the desired field product_parent_id it will easily associate with the main product).
