Simple Control, ISY, and Kepad button status

Is there a way of using the status of a keypad button as feedback for a button in Simple Control? The current “brightness” only works with the primary button that controls the load. In ISY, using the REST interface, I can obtain the status of secondary keypad buttons.

For example, the following url request returns the status of button 5 on a keypad:

and returns the following:

<?xml version="1.0" encoding="UTF-8"?> -<properties> <property id="ST" uom="%/on/off" formatted="On" value="255"/> </properties>

It would allow feedback for things like fan speed as well as the ability to use secondary buttons as device triggers. Can I accomplish this with a Simple Hub?
