That might be true but as pointed out it’s been two years since WLv2 has even been acknowledged as an active project. It would be nice to know if it’s still been worked on or not. The fact that this question keeps getting asked and TR doesn’t even give a vague reply concerns me.
Edit: I did find a more recent TR comment addressing assigning PLs for non-TR workouts/activities. Here, and then reaffirmed a few posts later in June.
