Question about yahoo dfs

Warning this might seem like a stupid question to some. My buddy at work and I started to do h2h dfs matches on yahoo against each other this season, just wanted try something different as we are in a dynasty and 2 redrafts with each other. Next season we want to get some more people together and do a dfs league. My question is when you set up a dfs league on yahoo does it pair people up in h2h matches or is it everyone is in one group and the highest score wins? So if it was 10 people there would be a 1st place on the week and a 10th place. I want it to be a group so I hope that is the way it is.
