AutoCAD Civil 3D :: Alignment PI Label With Lat Long / Station And Delta Angle

We are trying to label the intersection points on an alignment with the following info:

Sta:
Delta Angle
LAT
LONG

We can make it work with a Northing and Easting, but there is no option for a LAT LONG under the tangent intersection labels.  I tried to make an expression that would format a Northing as a LAT but it just gave me jibberish.

I was able to do it but adding a point at each PI and making a point reference text, but you then have to select a different point for each label....  which works but it is still a multi step process.
