"Close all background tasks" button!!!

How come there isn't a button or a function that allows you to close all background tasks of Creative cloud and other Adobe programs?
Every single time I have to go and press end task in the Task-Manager about 20 times, since there are about 10-15 tasks running and some jsut reopen after closing them if you're not fast enough while closing everything else...
That's jsut annoying yet it could be such a simple feauture...
