Stage view on telepresence endpoints

We need to be able to move participants to stage view on Room Kit Plus / Pro during Webex Meetings or Webinars.

For hybrid sessions e.g. panel discussions with in-room and online participants we need to show online panelists in the room (on a projector connected to Room Kit Plus or Pro).
Currently we use grid or stage layout but we cannot control which participant we want to show. We see participants that are not relevant for the panel discussion and even non-video participants are shown.
We would like to be able to control which online panelist can be seen in the room.
