Hi,
When I do this kind of thing, I edit in RH and only use the
generated word doc as a ticklist to work through. Having said that
you can copy the text of any changes into the RH doc.
Once each change is completed add the word "Done" as a
comment on the word doc and you'll then have a record that you've
checked off each change as you've done it.
Importing the word doc approach would in my opinion be a very
bad idea and you'll generate a lot of work for yourself as you'll
be dealing with more than just the changes that way.
In general keep things as simple and straightforward as
possible.
Hope that helps..
