[BEDROCK] Add more commands to quick select

On legacy console editions, "Host Privileges" allowed split screen gamers to do simple commands like change game mode without bringing up a keyboard. On Bedrock edition, a "/" button has been added to recreate this, but is limited. I would like it expanded to include features for legacy console edition, specifically change game mode and certain gamerule commands. Why do I want this when you can just type it? On split screen console sessions, bringing up the keyboard makes it so no one can play until you are done typing, which takes some time, especially on Xbox One and Nintendo Switch(docked). Thank you for your time and please vote.
