Referencing Local Alarm Pipeline Properties

I'm working on an alarm pipeline and I've set some local properties. One stores a full roster and the other is an index that gets incremented over time. In my notification block I'm using a calculated roster and I'd like to reference those two properties so I can work through the list of people on the roster. Calculated rosters rely on python scripting though so I'm wondering how (or if) local alarm property values can be referenced in a script.

Using event.get('propertyName') will allow you to reference the property
