Testing for Cyclic Expression that has been selected in a Line Graph

[#1]

I have created a Line Chart that has 2 dimensions (Month and Location) and 6 Expressions that have been grouped together. On the graph, the Cyclic Expression Group button shows up and works fine cycling through the 6 Expressions.

What I want to be able to do is have a specific Reference Line show up on the Graph for each Expression that is selected - these are different Targets for each of the Expressions. I have been trying to test to see what is the active Expression in the Cyclic Expression Group but can't find an automation field that will accomplish this. Since the Cyclic Expression button also creates a text field that shows the seleced Expression, there should be a way to test for this in the Reference Lines section.

Does anyone know how this might be accomplished?

Thanks in advance!
