How to allow only a single contact to call you in a Galaxt s5 phone?

[AC Question]

I got a Samsung Galaxy s5 device. Is there some sort of a "white list" where only people on that list can call me? What I want is to go to sleep and at night change the phone sound's mode to "Mute", but be able to receive calls from only a single or several people of my choosing (which their call will override the mute mode and will make the phone ring) until I change the sound mode back?
