Can Butler add a due date to a checklist item?

[Jessica Raden]

I've figured out how to use butler to get a new checklist item to appear when another is checked but now I can't figure out how to get butler to assign a due date to that new checklist item. It seems I can manually add in a due date to that checklist item but can't get it to automatically happen - the action just creates a due date on the card. This task will always be due the same day the other is completed.
