4 channel nfl mixed up - DirecTV

I have spent hours on chats in an attempt to select the four NFL games I would like to watch. Three CSR's said I can change the games that are preset, but none of them was able to walk me thru on how to do it. Does anybody know how to make these changes? If not would it be possible to open another channel with the other 4 early games? Going into week four would be nice to have a feature that could be used.
