You can make a pseudo-schedule for this sort of thing.
Simply drag the area note from the zone or area over to the place you want it to show up.
I have done this before with title blocks and some simple schedules I have drawn on the elevation sheets, site plan, etc...
It's not actually an interactive schedule, but it will keep your area summaries automatically updated when you change a zone or fill.
