Can a motion for a substitute attorney be made during a pre-trial hearing?

During the July 25, 2012 hearing, defendant's attorney requested a trial continuance. In response, defendant complained that a courtroom had not been available on June 12 to hold a Marsden hearing and that he was annoyed with his attorney and the trial delays. Defendant, however, did not make an unequivocal request for a new attorney or request a Marsden hearing. (People v. Dickey (2005) 35 Cal.4th 884, 920.) "'"Although no formal motion is necessary, there must be 'at least some clear indication by defendant that he wants a substitute attorney."' [Citations.]" (Ibid.)
