One can define any [ virtual_sites* ] directive manually in the topology.
pdb2gmx can build some types of virtual sites, but you'd have to tell us
specifically what it is you're trying to do if you want anything really useful.
Soon I will upload a patch that will make virtual site construction easier,
and intrinsic to pdb2gmx. I just need to find the time to work out the kinks...
