Raspberry Pi, WebIOPI, 8 Channel Relay--how to address individual channels?

I have created a Device Handler to handle my garage and am working on getting my irrigation to run on the same Raspberry Pi. The issue I am having is I want to create the Smart App to be able to create scheduling for my irrigation, but I am unable to select the other channels in the relay as seperate switches. It will only use the default switch associated and I can assign a specific channel to each.

Any suggestions on how I could make the seperate channels of my relay available to the SmartApp?
