You can specify for the 30 meters that the athletes have 2 attempts. However, you can only specify 1 start time. Also, the heats remain the same for attempt 1 and attempt 2.
An event unfortunately cannot occur 2 times within 1 category (at different times with different heats).
You can also work with semi-/full finals and set that everyone automatically qualifies for the semi-/full final.
The final is then 'attempt 2'.
