Some available properties missing from "Events" source list

I use a 7-segment Arduino screen with SimHub, and I'd like to create an alert that displays "LAP DLTD" if I exceed track limits in Race Room Exp.

There is a rawdata property called CutTrackWarnings that returns a binary result.

The problem is that CutTrackWarnings isn't showing in the Controls & Events section. In fact, I'm not seeing any rawdata properties at all. Is rawdata not usable for event triggers?

Or -- is there a way to use nCalc to create an event and trigger? It looks like I only have access to nCalc inside the Arduino "New Screen" dialog as a way to calculate a displayed value. I don't see anywhere to use if() statements to toggle visibility the way you can in Dash Studio.

Ex: if([CutTrackWarnings]=1, DisplayScreenFor1s_LAP DLTD, 0)
