Interesting idea but the label tool is not available inside the preview window. You can add text, but not autotext.
However you can add any information about each window in the schedule itself, so you can schedule the glass type by loading that parameter into the schedule list.
You can't link a section, however you might be able to creatively think about your window numbering system to help with cross referencing
