In order for new names to be added to OOBs the names have to be included in the master Names.xml file, or, via a mod. The easiest and fastest method is via a mod, as I will explain here.
Basically, with this mod (attached), your complete edited OOB will be copied and the OOB names transferred to a file named 'LanguageEnglishMod.xml', which will essentially register your new names when this mod is enabled in Modifications.
Once the mod is copied to the Mods folder, open it and copy your edited OOB to the OOBs folder. Next, execute (click) the 'OOBTONames.exe' app. Follow the messages in the app window provided, there will be two. Once completed, you'll find a newly created 'LanguageEnglishMod.xml' file, containing your OOB names. Move (cut/paste) this new file to the Layout/Media/Language folder, overwrite the original 'LanguageEnglishMod.xml' file.
Feel free to make your own mod using this mod's structure. You can include the 'OOBTONames.exe' app with a new mod or not, but hang on to it for future use. Not sure if it was included with the game, maybe the SDK, but it was developed by the SOWWL team.
Unzip and Copy to the Mods folder:
