Currently it is only possible to define the burndown chart criterium in the board configuration globally, which will affect the reports like velocity chart or burndown chart. Ideally it would be possible to switch this while viewing the different charts, taking the one in the board configuration as a default.

To achieve the same, i currently have to create a clone of the original board and then change the criterium there. This is of course is feasible, but gets a little frustrating, when you add/remove e.g. quck filters, swimlanes etc, as you have to do this to all the clones. As there is not such thing as "private" boards or marking boards as favorites, it also gets a little confusing after some time, when someone searches for a certain board.
