Before I upload .usr files, I delete what is on the unit and upload what I select. This prevents waypoint mergers. Of course, I always save stuff before I delete anything. Habit. You can also name/rename your saved files with the Lowrance too.
You and I work waypoints on the Lowrance the same way. I prefer to have a file on the SD card for each place I fish. That is not currently possible on a Humminbird.

It takes some work to manage files this way but it is worth it.
