Does anyone know if it is possible to do a mass import of patient information into Dexis (mobile x-ray)?

I'm interested in being able to import SM data (name, SSN, etc.) into Dexis prior to performing mass events to save the data entry time during the event. I don't have Dexis in my private practice and have only used it briefly doing mass events and couldn't find a way to do an import. Has anyone had succes with writing directly to the database/data files Dexis uses?
