We have our surface/contours/contour labels set up already(its a beach). We have custom contour lines to represent low water, high water etc as well as a label style that labels them appropriately. However 1 of them falls basically on the 10' contour in part of the survey, so the 10' label and the high water label get in each others way. can i somehow make a contour label that skips the 10' contour?
