Distribute plugin?

I have a 1.12.2 minecraft server and for this i use bungeecode here is my problem

namely I have a lobby server from which you can go to the bedwars lobby server and if you enter this round you should be on a bedwars distribution server from which you should be able to access the bedwars world with a multiverse core without having to briefly distribution server joint and now I need help how to do it how I can make it that you click on a sign on one server and then in the other server it comes into a round

Do not understand exactly what you mean, but when it comes to signs with a Bedwars server (waiting lobby), use the BW plugin Bedwars-Rel!
