Mapping creator attribute in desktop integration

I recently added some custom attribute mapping in Desktop Integration per the instructions in document CS36657 (http://sv-hou-cadls01.cjes.local/Windchill/app/#ptc1/tcomp/infoPage?oid=OR%3Awt.doc.WTDocument%3A135716&u8=1)

It sort of works, but when mapping the "creator" attribute from Windchill to the "Created By" attribute in Office, the username (e.g. - bsmith) is what is displayed in the Office document.  I would rather the full name of the creator be displayed (e.g. - Bob Smith).

Does anyone know of a way to map the Fullname field of the creator attribute to Office instead of the username field?

Any help is appreciated.

Thanks,

Joel
