Why isn't there a way to view total mastery

Now as someone who plays a very small champion pool, I do not have a very high mastery (like 86 or something). But I would like there to be a way for me to be able to see all of my points combined for every champ. Because I have a 135k on Annie and over 50k on both Ahri and Lulu with like 10 other champs above lvl 4 mastery. If I could see that I have like 400k mastery or whatever it is I would be happy because I like comparing stats with friends and other players because I am about that life. Welp that is my idea um erm erm erm hi. If I put this is the wrong place pls tell me so I can move it (I can do that right ?) thanks firends!
