Any way to implement internationalization in UIX side?

To implement internationalization in UIX side we used VaultExtensionMethod to retrieve corresponding UI text, but for some options like dashboard title (dashboard as pop-up window modal) and the context menu, when right click on an object, we couldn't be able to apply internationalization. 

For example, we have tried setting the m-files language to Italian, and we get the button text (within html body tag) as localized value but cannot change the title (within html head -> title tag) - Custom Menu Title to localized one. 



Also for the context menus below we cannot localize the Custom Menu option- 




Any way to achieve localized text from UIX for the above scenarios?
