There should be an option to save a certain number of different troops for different attacks. For example, I am always using the same number of troops in a Barch attack (e.g. 40x Barbs, 40x Arch, 40x Gobs, 12x Giants, 10 WB's). If I could just hit a button and have those troops queued up for training, that would save me a ton of time so I'm not manually selecting X number of each troop.

Similar to having 3 War Base layouts and 3 Home Village layouts, you could have 3 war troops (GoWiPe, GoHo, GoWiWi, etc) and 3 loot troops (Barch, Lavaloon, etc).
