A suggestion. This is the schedule for group A. Make exactly the same schedule for group B.
The men (in blue have names 1 to 8 ) and the women in pink have the numbers 1 to 8.
So male 1 and 8 starts against woman 2 and 6. You could change the courts between rounds if you dont want player 8 to play at the same court all the time. There are 14 rounds per group but you can stop whenever you like. I am not an expert on this so perhaps you will get better advice from some of the other members.
