How to set Workout all Outdoor Walk to default to "Open"

Apple watch series 3 I cannot change the default workout goal on outdoor walk to open. Default is now 16 minutes. I want it to set it to "open" so that when I select Outdoor Walk I don't have to manually select "Open" each time. The three dots method will work for a single workout but the next day I have to go select them again and select Open workout type again. No matter what I do it defaults to 16:00. Help, this is very annoying. Btw, I've already reset the watch multiple times to try to solve this. Thanks.
