Rob, I've done this in the past and if I recall it's quite straightforward. Put a suitable pad in the footprint and give it a pin number that corresponds to the thermal pad under the chip. If the pad doesn't have a pin number in the part specification, make one up. Then in the symbol file add a net attribute and set it's value to GND:x where x is the pin number of the thermal pad. Just make sure that the spelling of GND matches exactly the spelling used everywhere else. If I recall, capitalization matters.
