Is it possible to set default subtitles?

I am watching a lot of anime with japanese audio and english subtitles. On chromecast (via android) there is this (possibly amazing) feature of automatically playing the next episode. However by default it does use no subtitles. I can select every episode separately and select the english subtitles and then it will use them in autoplay.
Same with sync. If I choose the subtitles on every episode prior to sync it will sync them just fine. But if I just sync a series without choosing subtitles first it will sync them without subtitles. Is it possible to just choose default subtitles for every series/library?
