I go back and forth between Mapsource and Basecamp a lot in planning trips. I usually to the track editing in Mapsource and then transfer the track to Basecamp to get a more complex picture. When Basecamp already has a track or waypoint in its database in starts putting numbers in the name. I usually find this annoying and I try to remember to delete old tracks before transferring new ones in. I have had a number of cases where I think I have deleted all old tracks, but still get the number when I import a new one. So the question is: Is there any way in Basecamp for searching for all Lists where a given track or waypoint is used? I did a little searching and couldn't find this. Thanks.
