Now you choose to bulk update the subscription properties of all products in a collection. 
From any collection details page, you can choose to bulk update subscription properties for all products in that collection. You will be taken to a page, similar to the product details page where you can select the subscription properties you want. We are leveraging the power of Recharge’s async batch endpoint to allow subscription property updates of up to 10,000 products. Since a collection is just a grouping of products, you are free to update a subset of products individually or in a different collection without affecting any other products.
