Accessing MainSequence Context in LogToDatabase Sequence using Labview

I need to access to my local variables in the MainSequence in the LogtoDatabase Sequence file Callback. I tried using "RunState.Caller" in the Sequence Context of the VI connector pane but no luck. I'm hoping I don't have to use parameters to access variables in the "MainSequence". Is there a way to map the Sequence Context of the MainSequence to LogToDatabase Sequence?
