Playstation 3 controller number LED

Is there any known method to send data to the controller to let it know what controller number LED should stay light, instead of all 4 LEDs flashing forever?

My question targets the Afterglow PS3 AP.2 product, which is connected via wireless USB dongle, so not Bluetooth. But I would hope there’s some common approach, anyway. My current effort has me searching http://www.ps3devwiki.com/
