In a workflow we are currently able to add a wait for a specific time. Please add a random time between Min and Max mintues. ie. Wait between 5 and 10 mintes.
This is key for many situations but here is a good example. I want to Call Connect (bridge) salespeople to leads that came in during the night when nobody was around to answer their call. I setup this workflow to only run during working hours. So at 9am without this functionality all the calls will happen at once overloading the salesperson.
