They could add this to the normal campaign and Hades hell too, but that would make it somewhat easy to skip fights quickly until you get the right rng. 
The reason we have it in other modes is that the number of retries is limited e.g. in Clash.

skip in campaign and elite campaign doesnt make any sense.. even without skip theres literally nothing to do in game. At least enjoy those laggy long battles till you can. Also last DC update was in 2022 june 
maybe we will get some content on 3rd anniversary
