When exercises / workouts are imported from Health Connect, the import should take into account start/end times so that if a workout is strongly overlapping (e.g., within close proximity on start, duration, end times) that it is treated as the same workout. Google Fit does this well.

For instance, if a workout app (e.g., Alpha Progression) tracks and enters a workout and a fitness tracker also records the workout, then the workout is currently showing up in the app as two workouts whereas they should be combined into the same workout.
