I think that your best bet will be to execute the merge to a new document
and then use Edit>Replace to replace the country codes with the full name.
If there are not too many countries involved, or you don't need to do it on
a regular basis, a series of manual Edit>Replaces will probably not be too
much trouble. If there are more countries or this is a regular task, then
it might be worth developing a macro to do a series of Edit>Replaces by
iterating through a table that contains the codes and the full names to get
the findtext and replacementwith text to use.
