This feature will be implemented in a next release.

The lower bound obtained from a relaxation is only a bound. Its value
may depend, for example, on transformations performed by presolver or
on cutting planes added to the relaxation. So it does not express any
essential information.

You can use the C preprocessor (gcc -E) to prepare data files.
