The lifetime knob is a new thing, as you mention, and it can also be
renamed. Using the User tab may be better and more
back-compatible; although it can be renamed it probably won't, but I do
know of studios which do.
I think the reason there isn't an API for this is, because of time
constraints, no-one had time to ensure such an api would be robust in an
add/remove/shuffle-whilst-iterating scenario. I did look at doing this a
couple of years ago but there were a couple of other tricky (e.g. not
solvable between builds) edge cases to address.
Your solution is what I think ended up doing myself, in Python.
