Would be great to be able to specify additional text filters for Automatic Channel Collections - for example - all channels with a particular word in the channel name, or, to at least just be able to bring 'all' channels from a custom m3u through to a collection so the channel set could be managed in a secondary editor.
Automatic Channels are filtered based on what is currently airing, not on any metadata in the channel. The reason is because this changes all the time, hence the need for being dynamic.
Channel names never change.
It sounds like you just want better editing tools. You can select channels from a single source, snd then Add All if that’s what you’re after.
