Modification of dihedral torsion potential

GROMACS version: any
GROMACS modification: no

Dear GROMACS users,

Is it possible to use dihedral restrains to make the rotation along phy/psy angles in one direction easier than in another?


How one can modify a force field to do it?

Thanks in advance,
