independent subtitle sizes for 2nd subtitle, etc.

I love SMplayer because it's a front-end to mplayer.
But one thing stands in the way:

can we have the 2nd (and other) subtitles font/sizes to have their own setting?
I like to watch films with my partner, so I download Chinese subtitles and use Chinese subtitles as the main 1st subtitle (location bottom of screen). Since chinese characters are quite complex, I usually make the font sizes a little bigger.
I also like to display the english subtitles on as the 2nd subtitle (location top of screen)... but this doesn't need enlarging. However, when the chinese subtitles get enlarged, so does the english subtitles.. and it looks ridiculous and covers 80% of the movie.

The rendering of the subtitles is done by mpv and I think currently it doesn't provide any options to change the size or colors of the secondary subtitle.
