I have a shirt I'm selling that comes in 4 different colors. I would like to promote each color as it's own product so they all show in collections page. So, I've gone and created a product for each color. What I'm trying to figure out is how to show the other colors of the shirt as variants in each respective product view. I know Shopify doesn't have a problem with me using duplicate SKUs across these products, but I'm using Lettuce for my inventory management and that doesn't like the duplicate SKUs.
I've seen this in plenty of stores out there products will share the same SKUs, much to same reason I want to.
Is there any way to make this work?
