[gmx-users] symmetrical LJ binary mixture simulation

Hello, gromacs users.
I wonder if it is possible to simulate a symmetrical LJ binary mixture implementing LJ-PME methods.
The mixture is composed of A and B-type LJ particles and their sizes (sigma) are unity (=1). The interaction energy (epsilon) of A-A and B-B is unity, but heterogeneous interaction (A-B) is 0.5. While I try to apply LJ-PME method, the parameter, "lj-pme-comb-rule" is not supported for this case (Either geometric or LB combination rule is allowed).
Is there any possible way to work such an user-defined combination rule using LJ-PME method in Gromacs? If not possible in Gromacs, any simulation packages which supports those system with LJ-PME?
