Learning Plan Due Dates Change

Content

One of the benefits of learning plans I tell people is that they can be reused. So I have a client who took a learning plan with monthly assessments in it from 2012 - changed the due dates for 2013 and saved it with some new users and some of the same users mapped to it. It works fine for new people added to the learning plan, but people who had the learning plan mapped to them in 2012 still have the 2012 due dates. Is there a work around for this aside from re-building the learning plan?
