You can modify the FF and add the Cys-label parameters to the *rtp and
*hdb files, such that pdb2gmx will be able to use them. Another why is
use the original pdb as a starting point and modify the output *gto,
*itp and *top files.
Just remember that in anycase, it is better to copy the files into your
local directory so an change you made will not effect other simulations.
PS I can recommend on this site which can help you in the process
