Splunk Add-on for Cisco UCS: Where do I configure my tasks to use a peer index instead of the default it wants to use on my search head?

I installed the Splunk Add-on for Cisco UCS and can't figure out where to configure it to fill the "Index" drop-down with my clustered indexes OR modify a task from the CLI to use a single clustered index. Where do I configure my tasks to use a peer index instead of the one it wants to use on my installed search head?
