cfgmaker can only find interfaces that are available in SNMP and
at a place where it knows how to find them.  If the device doesn't
have SNMP counters for the subinterfaces, or if those counters are
not known to cfgmaker (for instance: they are in a private branch
of the MIB and it is not programmed into cfgmaker) there is nothing
you can do to cfgmaker.

However, if you know where the counters are kept, you can query
the device by manually crafting a config file.  You need to read
the documentation of both MRTG and the device.
