A sentence on a plea of guilty or nolo contendere may be imposed by a judge other than the judge who received the plea, if the defendant has been so notified at the time of entering the plea or if he agrees thereto at the time of sentencing.

Comment
This rule is not intended to proscribe sentencing by a judge who did not receive the plea when there are extraordinary circumstances which preclude the presence of that judge.
