Mirror behaviour option?

So I have 2 lights in my livingroom and used the option of mirroring behaviour so I could use the one icon within actiontiles for ‘livingroom lights’

But I’ve since swapped out one of the lights with an Ajax filament bulb and it’s very bright even at 10% so I like to always keep it at 1%, so the mirror behaviour setting will no longer be useful annoyingly as the other light is generally always set around 60%. Does anyone know the best way to tackle with so I can still have 1 icon within actiontiles? I’ve used a virtual switch in past but if memory serves that was a pain to set up and finicky and not always trigger.

Thanks all.

Perhaps scenes? You’d need one to turn on to desired level and another to turn off, though.
