Would it be possible to have a Volume Label produced in a similar way to the Area Label.
This could happen after the volume is computed in the Volumes Report preview, there could be a button to press for Label, then a dialog to select text from the Report, with an option to prefix something to the text. Then place the Label in the Survey View.
So for example a stock pile, if I wanted the Fill quantity I would Highlight 3580m³ and for the Prefix I would type SAND.
