I don't know of any such facility. Note two things: decompositions of free
energies into pieces are generally path-specific; with PME or GB models, the
energy is not pairwise decomposable, so that there is no rigorous result there
either.
But you still might learn some interesting things by accumulating the Delta-V
values in pieces; you would have to modify the codes to do this.
