Time Plus & Strings Drop Worse

We need a couple different scoring methods within the same match but have not been to set this up. Appreciate the help. Hoping someone can point us in the right direction.

Time plus (points) for overall scoring

Ability to have some stages run like speed steel with 4 strings and the worst time out of the 4 are dropped.

Is this possible? Appreciate the help.

Thanks you,
Jim B.

In time plus points format there are 3 scoring types available.
Time Plus (time plus time penalties)
Match Points (points earned)
Falling steel ( time to shoot down all the plates)

None are available with a, best of x strings, function.

Sorry
