It is great that the feature is now available but a serious deficiency is that we can’t set sender = contact owner. Without this it doesn’t make any sense to enroll contacts from within worklflows. Now we have to define as many branches as potential senders, and this makes workflows for bigger sales teams very complicated to maintain in case of personal and role changes.
