Just my thoughts...but, I would create a new customized dictionary to your specifications and make that dictionary the "default" dictionary (keeping the original "Custom.dic" in place). **This will be a tedious process.


To do so, click on "File" / "Options" to get te Word Options menu; then, click on "Proofing" / "Custom Dictionaries..." to get the Custom Dictionaries menu.


From the Custom Dictionaries menu, click on "New" and define your new dictionary name...then start adding your terms to the criteria you want to standardize. When complete, set this folder as your new "default" dictionary, leaving the former default folder in place.

Those are my thoughts. Other/Better solutions may be offered by resident Word MVPs/Experts/Users.
