(A) Appointment of Counsel. If the defendant has requested appointment of counsel, and the court has determined that the defendant is indigent, the court may appoint counsel for the defendant at any time during the proceedings under this subchapter. Counsel must be appointed if the court directs that oral argument or an evidentiary hearing be held.

(B) Opportunity to Supplement the Motion. If the court appoints counsel to represent the defendant, it shall afford counsel 56 days to amend or supplement the motion. The court may extend the time on a showing that a necessary transcript or record is not available to counsel.
