The ability to create and copy checklists(tasks) within cards.

For instance for, for service providers. I'm providing this client (project) with this service (card), that requires this checklist (tasks).

This is a monthly recurring service (card). We will do the same things for the client next month.

How can we, at the end of each month, recycle the (service's)card's checklist (tasks) or copy the same tasks into a new card without having to retype every task again?
