Default [Q] swipe palm screen catpure on custom rom

Hey guys, I've been on pac-rom for a while now, I really liked the palm swipe to take a screenshot on touchwiz just less strain on my physical buttons and much quicker, I was just wondering if there was anyway to get this back through an app or something or is it exclusive to touchwiz? i've already had a look at a few apps, some have overlay buttons which seems a bit cumbersome, some just give you the buttons again and give you editing options. Thanks
