constraints

Dear modellers,

is it possible with Modeller4 to define constraints instead of restraints? I would like to constraint a set of conserved residues to be exactly in the same position as those of the template structure, and was looking for a way to do this without setting explicit distance, angle and torsion restraints.

Thank yuo very much,
