Neither [] //2018-09-05 nor {tasklist:whatever} seem to work.
My use case was generating a checklist every month with dates filled in.
I tried just copying the page and mass-uncheck the checkboxes with $("li[data-inline-task-id]").removeClass("checked"), but that doesn't persist on page reload.
Jira didn't seem like the right tool because the task lasts over a month and subtasks seem too heavyweight for just a list of checkboxes.
