If you create a class named ComboBox in your project, and if you export that class, it will extend the native ComboBox class located in the GUI component. That way, by redefining the Add(), Clear(), _get()... methods (i.e. every method that read or write a ComboBox list element), and by using the SUPER keyword to call the methods of the overriden class when needed, you can add support for an item index associated with the item text. If you want to keep the original ComboBox class, just use another name, but then add "Inherits ComboBox" to that class.
