How much information has to go into these? If less than 15 items, see
Repeating Data Using Document Properties Content Controls and Other Mapped Content Controls. That may not work in Word 11. I do not know if Word 11 uses mapped content controls.
See also
StyleRef Field and
Repeating Data (Populating Multiple Like Fields). Both of those give methods that should work in Word 11.
I have not used Word on a Mac since Word 6 (around 1995) so am not the best source of information.
