training plan

I thought about something cool! I called it training plan because i have no idea how to call it other than that. But anyway the idea is that players could set themselves a plan of troops they want to train and then instead of going through al the Baaracks and waisting time by thinking how much troops they want to train over and over again they can do it by clicking one button that they've set up before for specific troops. Of course it would work only if they've got the amount of elixir (or dark elixir) tell me guys what do you think about this idea, sorry if that was sussgested before, I didn't see anything like that.
