Same ground reference for multiple ports

Is it possible to use the same ground reference for multiple single or internal ports? Some layouts I am designing have a finite ground plane with ground reference ports underneath several metal structures, each of which have single ports attached to them and the finite ground plane is the common return path for all signals on the single ended ports. It is not possible to attach multiple ground reference ports to the ground plane in the same referance plane.
