AutoCAD Civil 3D :: Use FDO Data To Populate Custom Data Field Expression

say you make some parcels in your project with custom data fields like: id_no, permit_no, acres_served etc. you attach an agency provided shape file via an fdo connection that has many fields of information like above.

when you right click on your parcel and do parcel properties you get a tab that lets you input the custom parcel data.

lets say you print an fdo map label showing, say, the id_no, provided in the shape file.  Then in your custom parcel properties for id_no you type that in.

is there a way to make an expression to put in the other custom parcel properties that will read, say, the permit_no(id_no) from the fdo like and put that information in the custom parcel property field?
