Yes, some parts of a document are replicated during a merge but others are
not. If all you need to be able to do is use the same macros on the machine
that did the merge, you should be able to put the macros in the template
attached to the merge document (ideally do not use normal.dot in this case).
The merge output document should be attached to the same template and the
macros should be available.
