Is there a way to do /1vs1 join {specific_arena}

[AL3XPI]

For particular reasons, my server requires that you can join a specific 1vs1 arena with a command. Let's say I have a 1vs1 arena name "x" set up in world "x", would it be possible to do /1vs1 join x, and have it take me to that specific world out of the multiple other worlds I have (y, z, a, etc), each with 1vs1 arenas?

The reason why I am asking this is that, when I tried it, it took me to a random world sometimes. It seemed like I had done nothing by adding the level name to the end of the command. If this feature really isn't available, or I'm not doing it right, please tell me or code it in. This plugin is very good and I will support your decision, no matter what it is @GamakCZ.
