To be able to delete listings on bulk or by supplier as a filter.

We have been told the only way to remove a product from magento is 1) Delete products in Magento 2) Select and redownload products to remove listings. (but have to find each one and relist) 3) Delete the product from Products section. I cannot select listings by supplier, so how can we do it. 1) better selection of listings and deletion of listings 2) When you delete a product remove the product and listing not just hide the listings.
