If you have accepted a plea to have your sentence served consecutive can you retain another attorney to have the sentence served concurrent

Once you have entered a plea of guilty in front of a judge and accepted that your sentence will be served consecutively, it is extremely unlikely that a judge will change the terms of that sentence.  Unless the judge explicitly states that your sentence will be served concurrently, it will automatically be a consecutive sentence. You could potentially pursue a motion for appropriate relief based upon ineffective assistance of counsel if you believe your attorney made a mistake and that mistake prevented you from obtaining the outcome that you intended.
