Amount of cut/fill

Hi,
I have created a a cut and fill drawing in Kubla using features extracted from 2 CAD drawings, no issues here; I get the tables with the statistics, volumes etc.
When moving the cursor over the 'proposed' drawing I am told the X and Y coordinated of the cursors position, together with the elevation of the proposed surface. Is is possible for Kubla to tell me the amount of cut/fill as the cursor moves instead of the proposed elevation?
Cheers, Tim
