Second (overlay) icon

it will be great if we can overlay a second icon on top of the Entity one. then the possibilities will be folds of what is offered in MDI. TV with WiFi, or BT … bulb, with flash to represent lighting energy … ideally we can control the size of the overlay icon and in which quarter to place it. however, half size (quarter area) on bottom right would be awesome.
after all it is all in the interface
