A while back I moved a bunch of deal (just people) to the leads inbox.  I'd like to mass convert them back from leads inbox to deal. Is there a way to do this?   

You may be wondering why?  Well, I had some automation setup for email drops and while these were not hot leads, at least I was tapping them on occasion automatically.  I haven't found a way to mass email to the folks in the leads inbox.. so I need to move them back to a pipeline.
