Not brilliant, but you can get annual totals if you take a screen shot of monthly steps just before midnight on December 31 each year. The program is pretty bad for this. The lack of encouragement for 5, 10, 15, 20 etc. million step milestones is also annoying.
or if you wait 11 months, you can get the total steps for all previous years in December. Or you can do some math to add/subtract monthly totals. It’s pretty crappy. Garmin should add a utility to calculate the totals between any two dates at leats.
