I have a project to track marketing requests. I would like to be able to create a new task/issue and assign a due date for each stage/transition. So the "to-do" due date would be before the "approval" due date, which would be before the "publish" due date, for example. Is this possible, or is there a suggested workaround for this? I am guessing I could add custom fields for each due date, but I wanted to see if there was a better way, first.
