Horn Feature

Hey guys,

I am not sure if this has been requested already but this problem has been frustrating me forever. I am referring about when a unit/units is/are stuck destroying a wall even if a wall just opened up. It would be awesome if there is a "Sound the Horn" feature or any feature that informs/alarms stuck units and make them stop attacking the wall and find their supposed route. I am not sure if being stuck is a feature of the game, but I don't see any reason for it.

Having this feature would increase accuracy of attacks and interaction of players. People won't just be happy to dump their troops and hope for the best now. They can actually have the option to watch the battle and "sound the horn" for whenever their troop gets stuck... or they can just leave them as is. The good thing is, the feature is optional but gives more control over your troops for people who actually cares.
