Hi Shane Sholdice,
We are aware of this drawback. Currently it is not possible to retain the FetchPlan attributes while regenerating the class. We are in the process of implementing an improved FetchPlan API with design-time checks (and not rely on strings) which would be easier to work with.
I'm afraid I cannot provide you with a workaround for the current problem.
We are sorry for the inconvenience caused.
