Is there any way (currently or planned) to be able to report on items on a Kanban board. Ideally I'd like to be able to get the duration that any one card sits in each column on a Kanboan board, and from there get the average duration that any card sits in each column. And preferably be able to prompt this report by actual completion date. So, for example, for all cards that reached completion last month or year, what's the average duration that each card spent in each column, to be able to compare month/year over month/year averages.
