One of the features available is the ability to display only tagged lithologies. By specifying only the Bed Code field (Seam Tags) be displayed, C-Master will select the 5" header box and only those lithologies that contain tags will be shown with annotation.

If you also request the elevation of the lithology to be displayed, the tagged lithology will have its elevation (bottom of the lithology) shown.
