multichannel signal spectroscope

Using spectroscope with multichannel signal cable works but I need to keep clicking on those dots to observe every channel,

I wanted to avoid to have to add a spectroscope for every channel.

Is there a spectroscope or an option that would show me the spectogam of all channels superposed, e.g. different colors, or in a grid? how it does it doesn't really matter much.

Suggestions?

Thanks
