Converting from Ellipsoidal to Orthometric Height

[DaveBodak]

We are working on taking some topographic shots and, from what we've read, it seems like Field Maps can only collect the Ellipsoidal height, even though Trimble Mobile Manager provides both the Ellipsoidal and Orthometric height.

After we collected the data (about 250 shots) we're looking for a way to convert over from Ellipsoidal to Orthometric. Does anyone know of an easy way to do this?

does trimble capture the ellipsoidal height in meters, then convert it to orthometric height in meters before it sticks it in the z-value of the feature's geometry column?
