Automation visual editor support for media_player volume level from input_number

Hi,
I am not sure if this is the correct place for this, is it a feature request or just user error, but here you go: in automation visual editor it is not supporting to choose a volume level from input number entity. This works fine by putting yaml in the automation for it. This would be great to just browse the value of input number entity value which is displayed at desktop for easy volume level changing.
It is very handy to have the volume level slider at desktop, so I wanted to use that entity in automation using visual editor. Hope I explained what I am trying to achieve.
