"Issue Templates" for recurring tasks

We are looking for a way to easily handle issues for recurring tasks, lets say a monthly newsletter. Creating a newsletter is more or less the same process every month. It has a parent issue and several sub-tasks. It would be super awesome to define an "Issue Template" (meaning a collection of predefined issues with predefined desciptions/summaries/etc) that we could select every month and that auto-creates the parent with it's defined sub-tasks. So basicall all we would have to do is change a few dates to have everything in place for next months newsletter.
