FrontLine: Is there a way to automatically inject an annotation?

I’m wondering if there is any facility in Gatling FrontLine that would allow annotations to be automatically and programmatically injected. For example, at the end of the ramp up period, or every time a certain condition is encountered, or whatever.

What would an “annotation” be exactly? How would it be displayed? Like the pins (right click on charts) in FrontLine?

That’s exactly what I’m referring to, the pins in FrontLine. I’m wondering if I can write code to automatically add those pins, in FrontLine. I would totally understand if the code for doing that did not do anything in the OSS version, or if the log entries generated by them were ignored by the report processor.
