Select from multiple external subtitles while playing

Hi,

is there any way how to select/change between the multiple external subtitle files (different languages) while playing the movie ? I only have an option to switch them on/off and select the encoding. But not the language/file.

I am using:
Serviio 1.5.2
Panasonic AS640
Panasonic Viera (2013) profile

Thanks.
Regards,
Pavel

Are the files named correctly - see http://www.serviio.org/component/conten ... es-support and then set your prefered language in the console.
