Cox contour

I have Cox as a provider and I have an hdhomerun device with the cable card. That only gives me the locat channels as all the rest are drm. I also have tv everywhere. I was wondering though with Cox you can view all your subscribed channels through the web with their Cox contour site is it possible to add that to channels via the custom channels? I see people have done that with mlb and Pluto tv etc. would it be difficult to do that with the Cox contour site?
