Allow the ability to filter your lists by what is streaming on your own selected streaming sites

My #1 most needed ability is to filter my lists by what is streaming on my selected platforms. That’s literally the only reason I have lists - so that I can see what is streaming on the platforms that I subscribe to. V2 does this fine, this needs to be added to V3. If I have a list with 1,000 movies on it, and I have no way of knowing what might be streaming on my chosen platforms, what good is the list? I would have to go through every single movie to see if it is streaming, and even on the movie pages it doesn’t give you an indicator of whether or not it is streaming on your chosen platforms the way V2 does. Please bring this back for V3.
