Can I select WifI channel via the App?

I have a mesh system for music - Sonosnet - so I am looking for compatible wifi mesh network.  All advice is to use a wifi mesh network that allows wifi channel selection.

So I am here looking at the RBR20 plus satellites.

My Sonos lets me select between wifi channels 1, 6 and 11 on the app.

I have seen on page 77 of the 2 year old user manual that I should be able to select the wifi channel for this device.

Can anyone advise me if the latest app has that functionality, or is it still accessed via login on laptop?

Thanks
