Wall Breakers Direction

I use wall breakers because it seems like letting your troops take damage trying to take down walls is just silly. But it makes me mad when the wall breakers go for any wall that they want, I mean, you should be able to choose the wall they attack. So I think that for wall breakers, you should be able to click where you want them on the field, and which wall to attack. if you don't click on a wall, that means you want to make 2 or more wall breakers target that wall. Its a simple idea that could make more people use wall breakers.
