Вы могли бы написать макрос для этого - вы бы использовали синтаксический анализатор Visual Studio для получения информации о членах класса.
Я написал похожий макрос. (Я поделюсь кодом ниже). Макрос, который я написал, предназначен для копирования всех конструкторов базового класса, когда вы наследуете его (полезно для таких классов, как Exception, которые имеют много перегрузок в ctor).
Вот мой макрос (опять же, он не решает вашу проблему, но вы, вероятно, можете изменить, чтобы сделать то, что вы хотите)
