In a sense, it was: IIRC, it was "used" to punch tape leader at the start of a message, but there were other possibilities which were never employed. The Murray code has "Figures" and "Letters" codes, which were used to shift the platen up for the "Figures" mode and down for the "Letters" mode. They weren't used for anything else AFAIK, so that leaves (32 - 2) = 30 x 2 + 2 = 62 code points. However, some weren't used, and I've always wondered why.
