Flag several items as Inactive at once

There should be a way to flag multiple items as inactive at once, or easily in the search page. Either a “flag as inactive” option under the “options” tab where I could enter the name of the product line and click “flag all as inactive” or a check box under the “quick look” so that the product page doesn’t need to actually be opened (I like how I can change prices and print labels from there). If a whole line of yarn is discontinued, I want to flag all of that as inactive, but currently have to open up dozens of individual product cards to flag them one by one.
