I was hoping I could export the contents of the Configuration > Channel / EPG > Channels into text, manage the data, then re-import the result.
There wasn't anything that I saw available to do that, but it's certainly possible, even likely, I'm missing it.
Is that possible? Otherwise, it's going to be a long slog going through 212 entries in the UI, checking the appropriate tag.
