When creating a PDF Portfolio (Convert --> PDF Portfolio) a default "coversheet.pdf" is created. In the localized language, the default coversheet looks like:
Optionally the coversheet.pdf can be customized to be anything. An example is:
The coversheet.pdf is found at C:\Program Files (x86)\Foxit Software\Foxit PhantomPDF\coversheet followed by the appropriate localized language code. For example, the German language version would be found at C:\Program Files (x86)\Foxit Software\Foxit PhantomPDF\coversheet\de-DE
In order to make this the default coversheet.pdf for all users at the time of deployment, utilize the Foxit Customization Wizard found here.
Navigate to Files and Folders --> coversheet --> [language]
Right-click the existing coversheet.pdf and select Replace. Navigate to the previously-created, language-specific, customized coversheet.pdf. Do this for any language needed. Make any other deployment modifications needed and save the MST file. Follow the deployment instructions found in the introduction to the Foxit Customization Wizard.
Note: Post-Deployment, the coversheet.pdf can be customized manually by overwriting the local C:\Program Files (x86)\Foxit Software\Foxit PhantomPDF\coversheet\[language]\coversheet.pdf file.
