I need to create a workflow in SP2013, where I have a list of approvers and SharePoint should iterate through this list and pick one approver at one time when a blog is created and assign him the task. for the next iteration, the next approver from the list should be picked up and assigned the task. Is there a way I can have any flag in workflow - SPDesigner to do this? and also keep a track of last blog creation and approver assignee?

Thanks
AP
