Copy Multiple Questions at Once

I know how to duplicate a single question slide.  I would like to duplicate multiple question slides at the same time.  Specifically, I am creating a survey for my employees regarding our vendors.  I am asking the same 6 questions about each vendor.  I would like to duplicate the set of six in one go (rather than one at a time).  It is very tedious doing it one at a time.  

Is there a way to do this?  Is there another way I could achieve the same efficiency other than copy/paste?
