Seems like it does for walking/running/cycling, they appear as icons on various graphs X (well, T, for time) axes... but there's no way to turn it into an actual activity after the fact.

Might have to do with the fact that during an activity it's actively tracking, full sensors blaring (notably HR) whereas otherwise it's lazier to save battery.

Still, I agree it'd be nice to have the option to either auto-create after the fact, or auto-start (and stop) live, or both.
