splitting and renaming tracks

Not sure if this worth the effort, but I have been manually splitting tracks, to have one track per origin to destination trip.  Then I have been manually renaming each of these tracks with a format like "StartDateTime - EndTime - Origin Location - Destination Location".

I seem to recall seeing a tool that would split tracks whereever it found a gap of a certain duration in the trackpoints, but I haven't found the website link for that.  Anybody know what that tool was?

If there's any tool that could automate the renaming of the tracks, that would be great too.  I don't imagine that there is any such tool, but if it could incorporate the name of the nearest POI or waypoint for the Start and End points of the track, that would be great.
