CCL:g98-optimizing more variables to the same final value

 Dear CCL users,
 I want to perform a geometry optimization in which several
 couples of dihedral angles have the same starting value and I`d like to
 let these couples optimize so that both dihedral angles within each couple
 can have the same value at the end of the optimization.
 How can I achieve such a course of optimization?
 Best regards,
 Jana Precechtelova
