I am trying to setup a filter in the Kanban view, based on the number of days an issue has been in a specific workflow status. I have setup a workflow where an issue will move from "Backlog" to "Planning". I would like to know if the issue has been in Planning for more than 3 weeks. I know you can turn on the "Days in Column" feature, and hover the dots on the Card to see the actual number of days, but I'm looking for something better.
