One of the principles of Kanban is 'Make policies explicit', part of that is to communicate to everyone when a card is allowed to enter an exit a lane.

In Jira we have no way to do this now.

I did a workaround/hack by creating a swimlane called "Rules for this Lane" and making a ticket for each column that is caught in the query of the swimlane. I used the summary field to spell out the rules.

My request is to have a field that I can write rules into called Policy for each configured column that will somehow be displayed on the board, whether by icon when hovered over or directly or a choice of both.
