Different fulfillers for product variants

I’m having trouble with

Hi! I’m trying to create a multivendor site organically within Wix (i.e., without needing to use the Webkul multivendor marketplace app). I was happy to discover that you can set different fulfillers to different products. See here However, for some products I have multiple variants (i.e., for the Apple product I have a green apple, red apple, and yellow apple). Each of these variants of apple will be provided by a different company.

So, how can I assign a fulfiller to each product variant WITHIN the product?

Thank you!
