I had a thought! Exported cave lists already report (among other things) station comments with flag entrance set against the elevation, and grouped by cave.
I have already experimented with redefining the map header so that depth is reported like; Length: 1232m Depth: 126m, from altitude 100m to 226m What would it take to make the station comments for flagged entrances available in the map-headers so that we could add entrance station comments and elevations? Like this? Length: 1232m Depth: 126m, from altitude 100m to 226m Middle Earth Entrance 202m Perseverance Cave 186m Hobbit Hole Entrance 150m Bruce
