You may already have this but attached is the 20 years old documentation for List Schedules -- kindly sent to me by David Maudin a few years back. I believe there was a later revision never published but it was not significant as I remember.
It took me quite a while to figure out lists and I finally decided it wasn't worth it. It does have some formatting features that the regular schedules do not have. And it has some calculation capabilities but with the new expressions and now Python , they are obsolete now. Also, it does not have access to all of the data that the regular schedules have.
I would not recommend it.
