It would be valuable to be able to add an item/subitem to every group within a board. Currently, our team has boards with standard tasks that need to be completed in each group of the board. Occasionally, additional tasks (items/subitems) are added to the standard list of procedures. We have to manually add the new tasks (items/subitems) to each group which is very time consuming.
For subitems, the additional tasks only apply to certain items, so this feature would need a way to specify which items to add the subitems to. For example, if the item description = a certain value, create a subitem.
