Only typ /creative /hub, not /server create, /server hub?? HOW

Hello!
I currently have 5 servers (hub, SuvivalGames, games, survival, creative) paired with bungee but when I should switch to another server I have to write / server <then the server I want to go to> have seen on the giant many other servers that one can only can write / <which server you want to go to directly> without having to type / server first? Is there a plugin? If someone knows, write here then, WANT help: D

Thanks in advance!
