Just make  "non-default" management classes with the archive retentions you
need... then have the user archive to a management class that fits their
needs for long term storage...  Below are the management classes I've
defined for one of my domains, each management class directs the data to a
specific storage pool and/or keeps it for a unique period of time (based on
how the data is stored, backup or archive)
