[gmx-users] restraining atoms to the plane at the bilayer center: pull code ?

The manual does discuss restraining to a plane, but this must be the plane
in which the atom is already present.

How about restraining the atom to some other plane? For example, how about
restraining a phosphate group initially at the lipid-water interface to the
bilayer center (for whatever fancy reasons) ? Won't this require pulling the
atom to that plane first?
If it can be achieved using the position restraints alone, it is not clear
to me how to do this?
