Currently Magento 22.214.171.124 allows to show only a single attribute on the listing page as a swatch (product details page can have multiple attributes showing).
Since I've 30+ manufacturers (and each has about 20+ colors), I've a separate color attribute for each manufacturer. I would like that all of my different color attributes will show on the listing page.
How can I make it happen?
Thank you in advanced for any tip.
