[Nauty-list] Processing automorphism groups

I recently started a project that has a number of requirements, most of
which NAUTY satisfies out-of-the-box. There are a few things that I've
not been able to crack yet by reading the NUG and the source code.
Is it possible to determine the number (count) of isomorphs of each
graph output by geng? I have looked at the statistics, the examples
in NUG and the nautyexX.c files, to no avail. Am I missing something
I would like to output this count for each graph in a custom
OUTPROC routine that calls geng as follows:
Graph 1, order 3, 1 isomorph.
Graph 2, order 3, 3 isomorphs.
Graph 3, order 3, 3 isomorphs.
Graph 4, order 3, 1 isomorph.
Note that this is the output from 'geng -lv 3 | listg -at' to
which I added the isomorphism information.
