Change Requested By

We often have Workfront admins set up projects for groups/teams. When the WF admin is setting up the task list all tasks are 'requested by' that admin. When the project goes live it's handed over from the admin to the group/team. Then when comments are made they go to the WF admin because that's the requester, not the group/team it should go to.

It would be great to be able to change the requested by field on a task.
