I suggest an option (checkbox) for the team games to swap opponents in half-time. This would make a team-game a match between the two teams, rather than two separate pair matches.

I'd prefer to see a way to link a match with a previous one, inheriting all characteristics but the players (to be set up). That allows what you propose (you have to set up players twice, though) plus multi-session, multi-players matches.
