Zope does not yet have management pages for mappings.
But, of course, you can create them.

When you implement the nested mappings with persistent classes
(e.g. "PersistentMapping" or a "BTrees" class), then storing
them should be painless. With normal dictionaries, you
should not forget to inform the parent object about changes.
