LG webOS - Switch to HDMI CEC Connected Inputs

Hi,
I have an LG CX with a Denon Reciever and multiple inputs connected to the reciever.
I now want to switch to those inputs in Home Assistant. Using the normal HDMI2 Input does not work correctly as the Reciever itself is selected, but not the correct media player, leading to me not being able to control the respective player using the Magic Remote Later on.

I tried searching the documentation for anything that could help but I wasn’t able to find anything. When running the get_inputs command in aiowebostv this is the output for the HDMI Port in question:

{

    "label": "HDMI 2",
    "port": 2,

      {

        "portId": 2,
        "uniqueId": 4,

      },
      {
        "id": "SIMPLINK",
        "portId": 2,
        "uniqueId": 5,
        "vendorId": 1485,
        "physicalAddress": 8192,
        "depth": 1,
        "osdName": "AVR-X1600H",
        "cecpDevType": 5,
        "cecpNewType": 9
      },
      {
        "id": "SIMPLINK",
        "portId": 2,
        "uniqueId": 11,
        "vendorId": 1099,
        "physicalAddress": 9472,
        "depth": 2,
        "osdName": "SHIELD",
        "cecpDevType": 4,
        "cecpNewType": 9
      }
    ],
    "subCount": 4,
    "favorite": false
  }

Is it in any way possible to switch to one of the inputs in the subList? Or does LG simply not expose this functionality?
