On the Kanban view for your team is there a way to build columns based on status thats for your team/GroupIe not using the default system statusI want to add unique status, that aren't visible to everyone as part of the system status

In order to add a custom status to a Kanban view, the status has to be a Locked status so it would show for all groups.

BUT, I believe once you got the status added to your Kanban view you can unlock it and hid it from the groups that shouldn't see it.
