Advertising multiple streams

Hi Nordic Team,

I'm currently working with the nRF5340 Audio DK to broadcast multiple streams, where the receiver can select which stream to listen to. To the reciever, this would look the same as if there were multiple gateway devices present.

Using this post, I was able to set up multiple streams on the device in NCS v2.6.0. However, to allow a receiver to select which stream to listen to, I would like to advertise the streams with a unique broadcast name. Currently, I'm trying to advertise two streams, one using the BT_AUDIO_BROADCAST_NAME, and the other using the BT_AUDIO_BROADCAST_NAME_ALT. However, it seems as if the advertisement packages, containing the broadcast name, are tied to a broadcast source, and not to BIS streams.

So I'm wondering how to move forward from here on out. Is there any use creating multiple broadcast sources on the same device? Or am I missing a configuration option that would help me in my use case?

I'm attaching my prj.conf:

# nRF5340 Audio
CONFIG_NRF5340_AUDIO=y
CONFIG_SAMPLE_RATE_CONVERTER=n
