Sorry to say but it's not possible at the moment. These features are not in DMM version and also the process for adding story and hero scenes are different from kamihime/eidolon.
Honestly, I made this player mainly for English community and did not think that DMM player would use it
.
Anyway, since you asked for it, I will try to integrate story and hero scenes for DMM version but you will have to wait till weekend since I'm pretty busy on weekdays.
