Yes, I think so. The simplest way would probably just be to create 5 bets and just say "Who do you think will be in top 5?

If your candidate is in the top 5 you win.

You can do this 5 times with different candidates and then this should be the same setup, no?

Or a more complicated way which is more a mirror of the current setup would be create an event with an outcome for every combination of candidates as part of the top 5.

This would just be a single bet where you pick your 5 candidates.

Edit: Oh, I think I misunderstood. The bet is not about who is in the top 5 but the actual positions in the top 5. But yes, that is also possible.

Then you just create 5 bets for every position and pick your candidate.
