Interval training for swimmers.

I am curious of this myself...I can confirm "set" training with customizable workouts and customizable interval (not intervals) is there for running and biking. Nothing is there for Pool Swim, and I don't believe you'll be able to create them and add them since the menu options aren't there. I can't confirm, but I'm almost positive, you won't be able to do this for Pool Swim with the 165, which is kind of sad now that this is on other watches $250 and less. Also find it silly that the "Intervals" option only has one interval which you can customize. Anyone training knows you should have many multiple types of intervals...so if you have an interval, you have to chance it every time. Kind of lame, though I get the 165 is a dip you toe in the Garmin ecosystem device...but why not include a simple interval for swimming as well. Garmin Swim 2 is old
