how to use sub or child channels

[jaud7of8]

Hello,
I would like talkiepi on my raspberry pi's to be added to a sub or child channel on connection.
Something like house/room#.
I found this closed issue
Fix for Child Channels in client.go #2
It seems the ability is there, but I can't figure out the syntax.
I have tried
-channel child-channel (not changing the syntax from before I created and moved the channel to a subchannel)
-channel main-channel/child-channel
-channel /main-channel/child-channel
-channel main-channel.child-channel
-channel /main-channel.child-channel
this is been added to the /etc/systemd/system/mumble.service
running systemctl daemon-reload
and service mumble restart after each change.

I looked at
https://github.com/dchote/talkiepi/blob/master/cmd/talkiepi/main.go
but was not able to see anything about sub channels.

I can have mumble on the pi's be auto assigned on connection correctly if I don't use sub/child/nested channels.
Any help would be appreciated.
Thanks

@dchote sorry for the tag. I was wondering the same thing, if it was possible to set up multiple channel-switcher or "shout to channel" buttons to isolate certain talkie-pi's in our intercom system.
