Many have complained about the lack of an EASY, QUICK, method (or dedicated button) for CC over the years, and much to my disappointment, Dish didn't do this for the Hopper system. I certainly hope they don't try to make some additional remote, likely inferior like the BIG button remote they offered, just for us CC people as I like having ALL the button on the current remote.
But there is still hope: right now, from regular viewing (no guide or any other display on the screen) you can press the BLUE button and a few of the Apps tiles appear at the bottom of the screen such as Dish Game Finder and Weather Channel apps and social media apps. So, Dish, could you add a Closed Caption tile that we can select that would turn on and off the CC? Of course, all the options would still need to be accessed via the menus, but adding a CC tile for on and off along with the apps when we press the blue button would go a LOOOONNNNNGGGGGG WAY to making it easy to turn on and off CC. We're BEGGING you, Dish. PLEASE!
