OPENCART - NEED IN ADMIN - SELECT WHICH PAYMENT API KEYS FOR EACH PRODUCT CHECKOUT

I have an existing Opencart website with a custom theme. We are introducing some new products which will require the payments and revenue generated from those products to be processed by a new credit card processor account. Same credit card processing company, just a different account with different API KEYS. When we create a new product, we will want to be able to select ABC api keys, or JFK api keys, or XYZ api keys. So, it would be 1 new admin area to upload api keys and create a name. And a second new admin selection in create products to select which set of api keys created in the above. Can this be done? Is this possible? Thanks
