Our business uses a refer-a-friend marketing program to get new users. For every new user recommended, you get a month of subscription free! Does the system accommodate that feature?

Essentially we need to push back the expiration date or next billing date by a month if a new user joins based on their invitation. Our system would be able to generate the list of people who get the "month" credit on a monthly basis. Is this possible? Many thanks!
