How can I tell which workouts I’ve completed?

I’m not following a specific training plan; I chose the workouts myself day to day. There are only a couple that I have completed that show the date I did them last, otherwise most of the ones I have done do not show the date last completed. Is this a bug; or is there a way to tell which ones I’ve done without resorting to the companion app and scrolling through my activities?

Thanks.

Hi use the Companion app gives you all of your workouts and rides
