Snapcast multiple streams/zones

Is it possible to set multiple streams in Snapcast for Hassio? I could not find how do I use this option ‘-s’

SNAPSERVER_OPTS="-d -s pipe:///tmp/snapfifo?name=Radio&sampleformat=48000:16:2&codec=flac -s file:///home/user/Musik/Some%20wave%20file.wav?name=File"

or the stream option

[stream]
stream = pipe:///tmp/snapfifo?name=Radio&sampleformat=48000:16:2&codec=flac
stream = file:///home/user/Musik/Some%20wave%20file.wav?name=File
