no there is no way to add more than one additional screen.
This is because whoever hosts the game has a screen, and then every game update the host sends an image to a server. Then all other players connected to the same multiplayer game all download that image from the server all at the same time, so they all show the same image.
Because none of the game code is running on the other players’ devices, only the host’s, we cannot change this behavior to make them download separate images. We can only change the image the host sends, so that is why only the host’s screen can be different.
