could you elaborate a bit more on this please?
I have searched for "Woocommerce Composite" and have found the following link - https://woocommerce.com/products/composite-products/
This looks like the same basic concept as Linnworks in that you bundle a set of items together as a kit and sell the bundle / kit.
If this is the feature that you are looking at then the answer will have to be a No as there would be no way to confirm 100% that the kit you have set up on Woocommerce matches the composite you have set up in Linnworks. We have to map at item level to ensure we can track stock levels.
If the feature is different to the one I have found please provide some further links.
