Change subtitles position

Hi Could You make the option in VLC for AndroidTV to display subtitles on the bottom of TV the screen, not on the bottom of the video file ? Most of the movies I watch are not 16:9 and have black bars, and I would like to display subtitiles on that black bar, not on the movie - but currenlty subtitles position is relative to bottom line of the video. In my TV I have an option like such (display subtitles on the bottom of the screen), also the option to move subtitles up and down (-/+ 5 position). If that could be done that would be great.
