Some fields available in activities appear to be lost in history or Connect.

There are some fields that you can put on your watch face during an activity. But, once the activity is saved, i cannot find them under "history" on the watch or on Garmin Connect. Are these fields preserved anywhere so that i can track them? Or, do i have to make sure to view them at the end before i save the activity and write them down or something if i want to track them? (that would seem very surprising/kludgey, if so). Here are some examples, but i don't know if this is a comprehensive list.

Thanks!
