Sport mode customization in Suunto App - not available for Triathlon ??

[Cocorun]

Hi dear community.

I use spartan watch and Suunto App on ios
I was just about to use the sport mode customization, in order to get specific view for the triahtlon sport activity.

Unfortunately, when I click on “create a new sport mode” in the suunto app, I get a list of many sports, but Triahtlon is not part of it.
So it looks as it would not be possible to customize the watch settings for the triathlon sport mode?
Is strange, because Triathlon is a core sport usually for Suunto, and I remember it was possible to customize it under movescount.

Has any one been facing the same issue, and eventually found a fix?

Thanks
