To add "Gacha games" as gambling, or at least at them to the "app block list"

Games like Genshin Impact, Summoners War, Guardian Tales and similar feature gambling mechanics (called gacha in this places) that psychologically manipulates their consumers into expending money into meaningless rewards, I don't know if is possible to make a deliberated list blocking access to all this applications or if they need to be manually added to the "App Block" list, but it would be great that parents, and possible gambling addicts, could block this applications at the DNS level, just as how is possible to block League of Legends, Fornite, and the like.
