I have received a gpx file with about 750+ waypoints in it from another user which was exported from his Basecamp. Each of the waypoints is associated with many many different categories but one in common. So, when I get info for multiple waypoints what I see in the waypoint reference field is an entry that says "<Multiple>" and another entry containing the name of the common category.
What I would like to do is to have a way to simply delete all the categories represented by the <Multiple> entry. Something like the method for the common category name which has a drop-down triangle revealing the option to remove this category from the multiple selected waypoints. The <Multiple> entry does not have such a drop down.
The way it stands right now I have to go through and edit each of the waypoints individully -- not a fun way to spend my time.
