Show More Advanced Exif Metadata in Bridge - Filter by flash settings

Ability to choose more metadata / exif / tiff tags to display in bridge 

Using other software like online metadata2go, i can see that my Nikon camera records lots of extra data points in the metadata, about the camera status.
Specifically just one called external_flash_status, however in adobe bridge we only have one setting EXIF Flash and it only shows 4 variables that don't actually reflect the correct flash settings in camera. 

?How can i add more information to display from the Camera Data exif panel or search meta options?

My goal would be to filter images by
