(2) If more than one item of property is physically damaged as a result of a common scheme or plan by a person and the physical damage to the property would, when considered separately, constitute mischief in the third degree because of value, then the value of the damages may be aggregated in one count. If the sum of the value of all the physical damages exceeds two hundred fifty dollars, the defendant may be charged with and convicted of malicious mischief in the second degree.
