        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the main-secondary assignments are to 
            be modified. 
        index
            An Int specifying the position of the polarity assignment whose value is to be modified. 
        value
            A SymbolicConstant specifying the value of the polarity to be assigned to the surface 
            whose index is referenced. Possible values are SPOS, SNEG, and TWO_SIDED.

        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the polarity assignments are to be

        assignments
            A sequence of tuples specifying the polarity assignments. Each tuple contains two

            - A region object or the SymbolicConstant GLOBAL specifying the surface to which the 
            polarity attribute is assigned. 
            - A SymbolicConstant specifying the overriding polarity value to be used for the first 
            surface. Possible values of the SymbolicConstant are SPOS, SNEG, and TWO_SIDED.
