I am attempting to create a dashboard that has two types of filters: The first being the filters that Kibana already provides. The second being a comparison filter that is additive to the existing filter. I imagine the best way to do this is to add another flag onto the existing filters as part of their meta data. From there, extend the courier to create two queries and then pass that through to the visualizations.
I'm having a tough time figuring out how to extend the courier to create and pass along these two queries.
Is there an obvious place in the code to do this?
