I have reminders like: Pay Phone Bill, due every month on the first. It would be neat to be able to type something like
'Pay %due_month% Phone Bill' and it pulls the month from the due date. When the task is completed, the repeat automatically creates a new one that would look like 'Pay July Phone Bill' and then 'Pay August Phone Bill'.

If it works, maybe also have %start_month% for task start date, or %due_day% would auto complete to 'Friday'

Thanks!
