Rolling Data Profiles help

We have a requirement to measure Forecast accuracy in Demantra.

To start with we would need to archive the Final Forecast series using rolling data profiles.  This needs to be done on montly basis.

1) Can we make use of seeded rolling profiles for this or do we need to define new profiles and series?

2) Any documentation available on how we can setup and use these profiles for checking forecast accuracy (Apart from implementation guide)?

Thanks
