Appeal deadlines and appellate relief requests are very specific. This will be true in the appeal you described.
If you are represented by counsel the question you have should really be posed to him or her. You really have not provided sufficient information to answer your questions anyway. An online forum in not really the appropriate place to do this complex a problem, in any event. I join the others that have answered as I recommend that if you do not have an attorney, you shoud contact your local state or city bar association for a referral to an attorney experience in social security matters.
Good luck to you.
