I agree. This would be a great to implement. You can quickly and easily change formations, tactics and players to use for different matches and opponents. For me when i play at home i like to play a 3-5-2 attacking formation but when im away from home and playing a stronger opponent i may play a 4-4-2 or a 4-5-1 counter attacking style. It would be beneficial if we could have slots where we can save our favourite formations and tactics etc.
