How to automatically end a scheduled run

Is there a way to automatically end a run on Epix Pro?

Use case: I have a 5k race. I add this race to my calendar or create a custom workout for it in Garmin Connect and sync it to the watch. But regardless, it will not automatically end when 5k is done. As a result, when I manually stop the activity, a few extra seconds are still added on top of that 5k and it's quite annoying. Yeah, I can see the 'clean' 5k result in the stats, but it would be beneficial for the user to have this option - auto end the activity, very similar to Garmin Coach activities,
