PDF Invoice On Email

Hi. Everytime a customer buys items from various vendors, each vendor receives an email with the order pdf invoice attached, on that invoice there’s all the items from the customer order. Is there a way to make the vendors receive only pdf invoice where it has only information about items bought in there stores, not on the other vendors stores? The purpose is to not let the vendors know what other items were bought by a costumer on other stores. I’m using WooCommerce PDF Invoices & Packing Slips. If it isn’t possible, how can i block vendors
