Better way to search for and add movies to My Rentals?

Perhaps I'm missing something. I've been using the Dish receiver menu interface to add movies to My Rentals. It's very slow and clunky. Is there an online or app interface that can be used to add movies to My Rentals? I was looking at the Dish Network app on the iPad. It's very easy to search and browse movies, but you can only watch the moving on the iPad. I would like to select a moving using the app interface, but have the movie added to My Rentals on the DVR. Then I can watch it on the big screen.
