Suggestion for global ults

So, some champions like have a global ult that makes a warning sound indicating that it has been casted. But a problem with some people is that they disable all sound in order to listen to music so they don't hear the ult coming. So my suggestion would be to create a seperate tab in opitions so we hear the global ults, kinda like the ping sound opition. We could leave the abilites sound tab on, but that would be uncomfortable to hear while listening to music.
