Make Total War grand campaigns allow 3+ players.

We wish for Creative Assembly (CA) to start allowing three or more players to embark on a grand campaign together, provided that this does not inhibit the single player, nor the multiplayer battle, side of the game.
This should be easier now that CA has implemented the new multiplayer campaign mechanic in Total War: Three Kingdoms that does not force the binary choice of either a head-to-head or a cooperative campaign, and simply allows the players to make that choice in-game.
We, the people with more than one friend, have wanted this for a long time, and this is the perfect time to start implementing this into the game.
Thank you.
