Can I make my FOP color Icons correlate to agent availablility

We use a FreePBX system for our corporate phone system we would like to have the FOP color icons indicate availability. green = available, yellow = DND/Away From desk, red = On a call/unavailable if any body could help me with this I would appreciate any tips. Or if anyone knows its impossible also let me know.
Thank You
