Custom labels in cross sections

I'm generating cross-section layouts for another person to draft for inclusion in public reports. I would like to be able to create labels for economic composites displayed on the section in the format "metres @ grade", eg 4.5m @ 2.5 g/t Au. This way I can export the layout and the draftsperson can pick up the text objects and use them directly. The custom labeling is possible in the scene viewer, but as far as I can see it's not available for a section layout. I have a fairly clumsy workaround at the moment where I make the labels for the composites in Excel then import the csv file with the labels as categories back into Leapfrog and use them in the section layout. Has anyone else attempted something similar with a better solution? The image shows an example of what i have managed to do and what I'm trying to achieve.
