 From a user application I helped with that added a set
of custom commands for a multi-IO PC-104 board.

#define CONFIGURE_PCMMIO_COMMANDS \
&Shell_PCMMIO_DIN_Command, \
&Shell_PCMMIO_DOUT_Command, \
&Shell_PCMMIO_ADC_Command, \
&Shell_PCMMIO_DAC_Command, \
&Shell_PCMMIO_IRQ_Command, \
&Shell_PCMMIO_Benchmark_Command

#define CONFIGURE_SHELL_USER_COMMANDS \
   CONFIGURE_PCMMIO_COMMANDS

I think you should be able to have a "shell_config.c" and
do it there.   It is based on confdefs.h and I know you can
do that with confdefs.h.
