I supply bundled Tracks to people for multi-week cycle tours and trust me, the 800** is a major PITA.
But the solution if you want Track-a-day, is to load them into NewFiles and reboot, rinse and repeat one by one.
Or to combine several shorter Tracks into a longer one, since the 800 is comfortable with a Track of 10,000 points. That's more than enough for any conceivable Arrow route, there and back.
** and/or 800 users - because a lot of GPS problems (whatever model) are down to a lack of empathy more than anything else.
