For duplicating folders of tasks (i.e.duplicating a project template), it is paramount to be able to apply a label to an entire set of tasks. I have created a Project label that allows me to label an item with the project number/name so that in an overview, the item lists which project it is associated with. However, each project has over 200 tasks in it to start. When I duplicate the template, I have to label each item with the project name label. I need to be able to apply a label to all items in a folder.
When in a folder, there should be an action menu that affects all items within that folder. For example, a few of those features could be, edit attributes, delete all cards, etc. If we could edit attributes of all cards in a folder, you could also edit the Start/Due Date attributes in a single folder for a two week sprint or apply the same deadline to many items.
