Using Merchant Center feed rules with supplemental feeds

You can apply feed rules to supplemental feeds to provide additional granularity for your product data updates. Using feed rules with supplemental feeds gives you greater flexibility and control over your product data. For example, you could create unique feed rules to update your product data for your price supplemental feed, and separate feed rules for your availability supplemental feed.
