Changing Siri's name on an iOS device

IS there a way to change what I call Siri when Ask her to help me? when i have my iwatch, my ipad and iphone, she will do what i ask on all three. Can i give her separate names on each device. for example I would like to call her "HAL" on my iPad, "Siri" on the iPhone, and "Buddy" on my Apple watch. This is so she doesn't answer on all three devices
