I am trying to save myself some typing in what I am doing but so far with
little luck. I'll try to explain this in something that looks like English.

I have a base document named Base.DOC. Periodically I need to import the
content of other documents into this documents. These imported documents have
reference fields included in them so that I only have to type something once
and the text is automagically inserted into other location in the document.
All well and good so far.

My problem arises when I need to insert the SAME document in the Base.DOC a
second time. When this happens all the reference information entered the
first time is entered into this new section.

Is there any way to create break or modify the reference so that when the
second or subsequent document is inserted the reference fields will refer to
the most recent entry and not simply the first entry?
