Playlist for training troops idea

The idea is quite simple actually.
Instead of always cycling through barracks every 20-30 minutes to create the same troop combo over and over again, why don't we have a playlist option where a player is allowed to preset and name a play list similar to music playlists.
So that I can have playlist for raiding(Giants,healers, barbs, and archers), a playlist for wars, and maybe a separate playlist with only archers,barbarians and wall breakers.

Each player could be allowed the option of 3-5 training playlist (can't really think of a cooler name right now :confused:).
And this will help keep the game fun and interactive. Thanks!
