Gamerule interface

I know there is already a place to setup the gamerules before creating a map in the 1.16 but I would really like is there was a gamerule interface for a world that was already created (like beside the optimize world button or something like that). I mean it would juste be a lot simpler and quicker to just press a button than to write the whole "/gamerule something true" especially if you want to edit all of the gamerules.
