Is it possible to bulk move objects to another Scope?

Currently, all objects have been created in Scope:Global.  Scopes have not been used.  Until now.  Now, there is a need for Scopes.

First Question: How can objects be moved, in bulk, from the Global Scope to a (new) child Scope?

Objects that need to be moved are Changes Reqeusts, Documents, Physical Items, Serial Items and Tags.

Second Question: Are Relationships affected by Scopes?  Do Relationships exist in one scope or another?
