Is Datafeedwatch the best solution for splitting product feeds for Google PMAX or is there something better/more user friendly? Shopify "Google & Youtube" app looks like it just syncs all of the product feed and I noticed Merchant Center interface has changed from the the time the product feed video and pmax video was recorded. Want to make sure we aren't showing our whole collection of products when trying to only push our best sellers, etc. kind of thing. Thanks!
