Enabling subtitles on all managed users

Does anyone know of an easy way of turning on all subtitles on for each of my managed users? When I create a new user subtitles are not selected when a user looks at a movie or tv show.

Unfortunately, this tool is still the only option to set language preferences for managed users:
