You get greater flexibility by not having the project repeat, but rather having individual actions in the project repeat. That way you can add actions to the project which will not be repeated, and there isn't a problem with the next month's actions not showing up because you haven't completed all of the current month's actions—the next month's actions aren't created until you complete this month's project with your approach. Just be sure to put a start date on the actions so they don't appear before their time, and you'll want the containing project to be either a parallel project or a Single Action List.
