Auto activity start?

Hi everybody,

Recently I got Vivoactive 3 (actually 2 of them) which I had to return due to being defective. So now I'm looking at Fenix 5s... I couldn't find any info about if it can do auto activity start like vivoactive 3. It's under each individual activity's settings in VA 3. You set up a threshold, like 5 min, and after that time lapsed, a watch asks you if you want to start record that activity. Is there such thing in Fenix 5s?

Also can anybody comment on vibration intensity of fenix 5s compared to VA3 or VA HR? I found VA 3 vibration is way weaker to my liking.
