Default [Q] Xposed module that allows one-finger notification expansion

I have a GS3 and am using a TouchWiz rom. I am on 4.1.2, but thanks to Samsung, don't have the one-finger expand notifications option in the notification bar. I have to use two fingers to do that, even though 4.1.2 supports it. Does anyone know of (or can anyone make) an xposed module that would allow single-finger expandable notifications on TouchWiz 4.1.2?
