Is it possible, two have a word document with two column, where the first
column is one document spanning several pages, leaving the right hand column
blank so as to add another document.

for example

Doc A                       Doc B

1. do not do this        1. do do this
as effects are            as effects are
negative                    Positive

the documents will be spanning several pages, i would like to manually
compare them without swapping windows/documents all the time?
