TemplateLiteral optional part

Is there a better way to handle optional chunk in

Schema.TemplateLiteral

Schema.TemplateLiteral

than to do ?

Schema.TemplateLiteral(
    Schema.Literal("required"),
    Schema.Literal("optional", ""), 
    Schema.Literal("required"),
);

Schema.TemplateLiteral(
    Schema.Literal("required"),
    Schema.Literal("optional", ""), 
    Schema.Literal("required"),
);
