Such a feature is not implemented. In principle, you could insert a call
to lpx_write_mps in lpx_intopt (file glplpx6d.c) to output the instance
created by the mip preprocessor (which generates the cuts), i.e. that one
which is passed to lpx_integer. However, it would be problematic to
interprete components of the preprocessed instance in terms of components
of the original instance.
