If the defendant is convicted of two or more offenses based on the same act or transaction, or constituting parts of a common scheme or plan, the terms of imprisonment shall be served concurrently unless the court expressly directs that some or all be served consecutively. Other sentences of imprisonment shall be served consecutively unless the court expressly directs that some or all of them be served concurrently. In the case of the concurrent sentence, the judge shall specify, and the court minutes shall reflect, the date from which the sentences are to run concurrently.
