I'm making a pretty standardized set of maps that include alphabetical labels for specific stream segments. As it stands, all my label leader lines snap to the downstream end of my polylines. My current workaround is to convert labels to annotation and hand-place them but this is getting to be a real time sink. Thus I ask: is there a setting I'm missing, or other way to get leader lines to snap to a line centroid?
