I would like to set up ratio spreads that might look like this:

3 short puts delta 30

1 long put +20 points

1 long put -20 points

1 long put -60 points

The entire option construct should be closed when the short leg is 30 points ITM.

In general, I would love it if it were possible to close entire option constructs based on the moneyness of individual short legs.
