Promotion Requests out of the box have an "Owner" role that is the initial creator. What's really nice about this is that in the Members table, you can change the "Owner" in case someone else needs to take over future tasks that would have gotten assigned to the Creator.
We have other Workflows that use the Creator role in downstream tasks, but there's no way to change the Creator. At best, all we can do is reassign the individual tasks after they are created.
How can a Workflow be configured so that the Owner role shows up in the Members table and can be updated just like on a Promotion Request?
