Hi,
On the Facebook Catalog Manager, we can sort products by custom labels ("Custom Label 1", "Custom Label 2"...up to 5). Is there any way we can set up these labels through Shopify on the products ? Heard there could be a possibility via the metafields, but it's nowhere in the docs, and I couldn't get a confirmation anywhere.
Did someone manage to implement this ?
Cheers,
Alexandre
