Unfortunately, this will not be possible. In order for this to happen, we would have to duplicate ALL of the Main Display formatting settings including the size, shape, and position of the text box. The road block that prevents this is the Main Display and Stage Display are often not the same aspect ratio and resolution. This means the text area is not always the same. Since this is often not the case, there would be too many issues caused by those who would try to use this option if made available.
