One item showing in multiple kanban columns

Hi Tiffany! This is not a supported functionality with the Kanban feature. At this time, an item will only appear once in this view, as the Kanba organizes the data by a single Status Column.

I love the idea though and our product team is eager for this kind of feedback to include in their discussions for future improvement. This feedback can be submitted directly to this section of our community page. Learn more here
