[Feature Request] autojoin in multiple voice channels

Is your feature request related to a problem? Please describe.

My server currently hosting multiple music voice channels that each has a specific theme. Currently I find that you can only use setvc for one channel and autoplaylist for the whole server.

What is your ideal solution to the problem?

Since you have to use setvc and autoplaylist to allow the bot to autoplay when an user joins, I think there should be an autoplay command. Also I would want autoplay command to be set in multiple voice channels and play different playlist assigned to each channel.

How would this feature be used?

1. Either join vc-1 and type !!autoplay <playlist-1> or type !!autoplay vc-1 <playlist-1>
2. Either join vc-2 and type !!autoplay <playlist-2> or type !!autoplay vc-2 <playlist-2>
3. Continue the process to every specific channel you want the bot to autoplay.
