Hi angelo licastro1,
Thank you for posting in the Microsoft Community Forums.
Wunderlist has been discontinued, and you can use Microsoft To Do directly. For special lists, you can search the web for how others are using it and help yourself better use Microsoft To Do by copying their format.
Also, this is a public forum, and for the sake of information security, you should remove the number in the question.
Best regards
Neuvi Jiang
