MusicCast source ignore

I am using the MusicCast integration now available in the UI
I was using the Yamaha integration with the “source_ignore” to reduce the long list of sources that I am not using.
I cannot find an option to ignore sources using the MusicCast UI integration.
I’m sure this is an easy fix and would love it if someone would point me in the right direction.
Thanks,

any news???

I was just about to post this same question, and then noticed this thread.

Does this mean there is still no way to “source_ignore” with MusicCast?

I have far too many unused options. The neat solution of the Yamaha Network Receivers integration was really handy. Has anyone found a work-around?
