I used this to organise my to-do list. Basically you add a new list on your IOS reminder call "Work" etc. On Siri, you say "Add Work reminder to call Annie tomorrow". Then it'll automatically add "Call Annie tomorrow" inside the Work reminder list as well as adding it to your Evernote.
If
New reminder added to list
This Trigger fires every time a new reminder is added to the list you specify.
Then
Append a to-do to note
This Action will append a to-do checkbox to a note as determined by its title and notebook. Once a note’s size reaches 2MB a new note will be created.
