Hey Cortana instead of double tap to wake

[Ken Nye]

Is there a command to have Cortana unlock your phone and just goto the home screen?
the 950/xl do not have the double tap to wake so I want to use hey Cortana instead, but I have to tell her to open a program to make it work. I want to say "hey Cortana open home" or "hey Cortana unlock"
any ideas?
thanks
