I have some questions about the E-Commerce catalog module in NetObjects

Question 1) Is there a way to move a product added to one e-commerce catalog
into another e-commerce catalog? Both catalogs are in the same site and
both were created with netobjects e-commerce catalog module. For example
one catalog might be "books" and the other might be "games". If some books
were accidentally added to the games catalog, would there be a way to
quickly move them to the books catalog?

Question 2) Another related question: Is there a way to split one catalog
into 2 catalogs?

Question 3) Is there a way to just reference database records from the
catalog rather than importing and/or adding items by hand.
