My sketch takes only a fraction of 32K, leaving lots more flash available than eprom, so I'm wondering if it is possible to save data in flash. I know I can load data as part of the sketch with PROGMEM, but I'm talking about adding more data to the flash later which I'd then be able to access via some PROGMEM like technique.

Flash memory is read-only, so, no you can't.
