Agile Classic cumulative flow chart with kanban

I am trying to use gadget for cumulative flow chart. But i cant do it exactly where it is very important: kanban projects. The gadget need a version but i do a continuous delivery and i dont have the version concept. As workaround i create a stub version "current" but i need to put all of my stories in this versio, wich sounds embarassing to me. The CFD works well on agile dashboard (withou versions) but not on the system dashboard and i love that feature to use jira agile as a information radiator.
