The limitation has more to do with the slider selection method. The longer the selection (i.e. 30 minutes versus 4 hours), the less precise the slider becomes. An easy work-around is just navigate to a waypoint far in the distance and a line from the iDevice position to the waypoint is drawn on the chart. Realize waypoints can be dragged anywhere on the chart.
