Yeah that random sequence generator is more annoying than manually sortinng out line-ups.

Fo this tourn, I would have basically taken 1 robot from each person and out them into 8 groups.

example

Martijn robot A in heat A
Martijn robot B in heat B
Joey robot A in heat A
Joey robot B in heat B
Kody robot A in heat A
Kody robot B in heat B

That way there would not be any clashes in terms of someone having two robots in the same heat. Individual matches can then be sorted easily.
