Universal Remote HR54-700 - DirecTV

AGGHHHH! Getting info from ATT is like pulling teeth... I just switched from Uverse to Direct TV today and I wanted to know if there is a Universal remote for DVR Model HR54-700? I have a Bose soundbar and the RC73 will control the volume but not the power. My old Uverse remote I would set to AUX and it would power it on and off. Does anyone have a model number for a Direct TV MADE remote (not a second brand manufacturer like Logitech, I have a Harmony but I want a remote for each family member). After 4 people asking my name and phone number, I finally got one to tell me a 66RX might work but it won't control everything or maybe not do it all right.
Help! Anyone.....
