A quick camera zoom to the battlefield when a ballista attacks.

Does anyone know how to disable this setting? When you order a ballista to fire, the camera suddenly jerks from a top-down view to the ballista that is firing, right in front of your face (by the way, the camera angle is strange; it would be more logical to view it from the side and slightly behind, so you can see where the shot is going). At maximum battle speed, this is constantly annoying. It's much more aesthetically pleasing and enjoyable to watch it from above as it attacks enemies. So, where can I "tweak" the settings to prevent the screen from jerking towards it during the attack?
