I'm looking for a BungeeCordPrefix system for Minecraft?

I'm looking for a bungee cordfix system for minecraft where you then have a certain prefix by permission.

What you are looking for does not exist. A bungee cord can't control the prefixes of the subserver. At most (as an example), you can download PermissionsEx, drag it to all servers, and then connect them individually to a database.

On Youtube, there are enough tutorials.
