I also have a BeforeBuild hook that will blank the Tag and Tag2 fields in the first field of my reports files. As for the Expr, my code only removes any of 3 lines that start with:

DRIVER=
DEVICE=
OUTPUT=

These will be the first 3 lines in the Expr field. I leave all other lines in the Expr field alone. See mlines(), alines() and memlines() in VFP help to get started on creating your own code to handle this.
