Whenever you setup a media player, you get a nice looking card with a three dot for a sub-menu:

It would be nice to add arbitrary input fields to this sub-menu to allow for more specialized controls. For instance, the webostv is a good start, but I have serial access to my television which would allow access to the television’s power savings, among many other settings. It would be nice to group these fields with the media player’s sub menu

The sub menu just opens the media player more info dialog which shows all available options for that tv.

Custom HASS setups might allow for more options, which is why i’d like to be able to add those into that sub menu, options that might not be what are exposed by the media player device.
