multiple prefabs in unet network manager

in my project each player have 3 characters to control as isLocalPlayer, but in Network Manager we can add only one Player Prefab. my question is how can i make the 3 characters as local players so i can use if(isLocalPlayer) for each one of them.

thank you in advance.

think of the player as the code that can differentiate between players. It can very well be just be an abstract idea of a player, the entity that can control three others. make it a prefab that in turn spawns the three controlables and let it control them.
as an example for an RTS, it wouldn’t even be a player, but the godlike entity that can select others, move them around etc.
