Cart66 auto update when Post is saved.

When I create a new post. I have 4 custom field values in my post: Title, Item number, Price, Colours. Then, i also update the same info in my Cart66 product backend, for them to be linked. As you can see this is double work if you have multiple sites. In the database, there is a table wp_cart66_products In that table i need these to be pupulated when i publish a post id = post id that is automatically generated it seems name = the name of my product which would be the name as my Post title item_number = the item number price = the price option_2 = the color choices When this exist in SQL, it means that is a product, which i can link to via a custom field value only needing the "item_number". I am not sure if "id" has to be the one that cart66 generates, or if you can make your own, perhaps make it the same as the Post ID?. This is a very very complex issue i am having and is not an easy task to perform. The conclusion of this project would mean that when i click "Publish" in my Post back-end, there needs to be a a new product in cart66 as well without any other interaction or windows. There can be one button i can press which add its to cart66, but nothing more.
