yes you would have to cancel your existing ressies in order to add.
I wouldn't do it because more than likely they are not going to have openings...they rarely do.
When I was there in December my cousin and her friend met up with us and we had a ressie that night. We decided to ask at the restaurant if it was okay to add 2 people to our table. It ended up not being a problem.
I would think you may have an easier time doing that and hoping that they get it OR have them call and try to get a ressie on their own if you can't get them onto your table.
