2 Club events ride togheter

It would be great to create 2groups in club events , so they can ride together or chase each other. My idea was to let 2 groups ride togheter on a differt course , but simular track. (Beach island loop / Volcano KOM after party). Both groups could ride togheter for 33 kms and split in round 3 at the volcano => 1 group continues on the beach island loop , the others could climb volcano. Same story for (Richmond libby hill after party / the fan flats ) and so on. When you create 2 groups in same event , they start with 2 minutes difference and on the same track.
