Signal Masts

Not to hard to create a Signal Mast from two signal heads, also not rocket science to create some Signal Mast Logic, but what I can't figure out, is how to enable the "diverging" (or bottom) signal head to change color:

The "Panel" is shown on the right hand side, and when you throw the turnout, or activate the main line (bottom line) sensor, the top (left) green signal goes red. Close the turnout and/or inactivate the sensor and the Signal Mast cycles from red to yellow to green pretty quickly. But where do you tell JMRI to do something for the bottom signal head (right)?
