Facebook catalogue varient pricing

How am I able to setup my Squarespace store to my Facebook catalogue that will include all my variant sizes, materials and prices for each product?

So far I have gone through with setting up the data feeds with my store but it's only displaying a single price per product without the variants.

I've been dealing with this as well for a client's boutique. Everything is squared away, but we can't configure how to get Facebook to connect to show variant images, without having to be redundant and re-upload products. Did you have any luck?
