@Egika Thank you very much for your input.
This is good news, I hope it comes to the Ocean, do you know perhaps? (All my previous Suunto watches did not hold up in the ice swimming conditions, so Suunto said the Ocean is the best fit, but updates seem to be lacking)
I will give it a look, must have missed it somehow.
I hope this Feature Suggestion post will have more swimmers suggesting features to improve swimming.
