I'm so sorry to tell that but we don't have plan to add this to version 3.00. You can try to do it your self, in final this will be compounded object from edit box, button and list box (list box contains scroll bar).
Temporary you can use MENU or List box and for simply replace just comment the old object definition and create new one with same name.
The eGUI I will send to you on email.
