For example, if I begin a workflow and find that I missed out a reviewer, I cannot "edit" workflow and add a new reviewer. I either have to start a new workflow for that reviewer or I have to cancel the current workflow and start a new one with all the reviewers. Is it possible to add another reviewer to a running workflow? If yes, how do I achieve this - can anyone give some pointers or helpful links? Is this something that can be on the roadmap as a future enhancement?
