Direct Closure of Windows on Mission Control

Why isn't there an option to directly close out of windows that appear on Mission Control? Right now I have to click on the individual window to bring the screen out of Mission Control view, then click the red 'x' for that selected window. This creates a large waste of time and clicks, especially if I want to close multiple windows that are open on my computer. I'm advocating for a similar mechanism that is used on iPhones, where you can double click the home button then close out of multiple apps rapidly on one "dashboard".
