Scoreboard and Music Commands Update

Hey there, I have a few simple requests for changes to the Scoreboard and Music Commands on Minecraft Bedrock Edition (not sure if some of these features already exist in Minecraft Java Edition). For the /scoreboard command, it would be nice if it was possible to display certain scoreboards in the sidebar to certain players instead of being able to only display one scoreboard to all players on a server. This would be helpful for our different modes on our minigame server that I am building with my friends.

As for the /music command, it would be nice if it was possible to play songs to certain players in the game rather than everyone when the command is triggered. It would also be nice if the music would not fade out if you got too far from the source, rather the music simply plays at normal volume no matter where the player goes until the music is stopped by a different command. Also, it would be nice if you could stop music in the /music command for specific players instead of all players. Perhaps you could just use @a, @p, @s, @e, and @r with these commands similar to what many other commands use when selecting certain players. Thank you for reading and please consider this request as it would greatly benefit the development of our minigame server that we've spent a few years on. Thank you.
