We just got a very nice Edge with the 'Sync' GPS system. Can it track the mileage of different users? Specifically, it would be nice to have a user setting (say, user 1) that could be used to track business trips, and another setting(s) for other purposes. I know the computer is smart enough - I just don't know if the designers were smart enough to include such an obvious feature. If it is possible, and the feature is there - I haven't been smart enough to find it...
