A lot of the stories in our backlog (OnDemand) are pre-assigned to individuals, but not all of them. During our sprint planning meetings, I (acting as the scrum master/facilitator) often need to move tasks in progress or to complete. Because I have auto-assign enabled, it always reassigns them to me.
I know I can turn auto-assign off, but the behavior I would really like is that auto-assign would happen only if the story is unassigned. I have already created a custom workflow, and I'm willing to put the logic in there, but I'm not that experienced with workflows yet, and I'm not sure quite how to do it. I would think some kind of conditional post-processing operation would work, but I'm not sure how to create a condition that is based on whether the Assignee is assigned or not.
Any help with this would be greatly appreciated!
