Has anyone successfully called a method in F5 that requires more than one argument using the Splunk Add-on for F5 BIG-IP?

I need to get all pool member monitor status into splunk. The F5 API has the `LocalLB::Pool::get_member_monitor_status` method which looks perfect, but it doesn't appear that the templating language provided with the Splunk Add-on for F5 BIG-IP allows calls to methods requiring more than one argument or parameter.
