Could there be some master list of all the heroes that gives us the ability to toggle them so we can mass raid elite campaigns. It’s so tedious to do it individually per hero. I’m aware that you can “raid all” for a particular hero, but when you’re looting the skill chips of 30+ heroes per day, it gets tiresome.
And after all that effort we still only get 3 chips for the hero 
And an expense of a lot of resistance.
