Presence function on buttons device

---

I have searched for it but came up empty…

Would it be possible to add a presence indicator to a buttons device button?
To be able to create radio buttons, or other ways to light up the button.

Config would be something like this:

    {
      "id": "buttons_id",
      "name": "buttons-name",
      "class": "ButtonsDevice",
      "buttons": [
        {
          "id": "button_1",
          "text": "- 1 -"
        },
        {
          "id": "button_2",
          "text": "- 2 -",
          "presenceSensor": "$id-of-some-boolean-variable"
        },
        {
          "id": "button_3",
          "text": "- 3 -",
          "presenceSensor": "$id-of-another-boolean" 
        }
      ]
    }
