I have a receiver (and TV) that is controlled as a media player in HA, if you go into the options, you can control some settings directly, in my example the sources in the receiver. I have posted a screenshot.
But i want to be able to control these “secondary options” directly, without going through the option button, preferably for both the receiver and TV on the same card. But is this possible? I doesn’t seem like these have their own entity ids.
