API checks: "AND" Operator for validation steps dependencies

There is a limitation on the creation of API checks, when the validation values are dependent on each other. Below the uptime API check behavior and what the requirements would be. The problem is a missing AND operator between steps/validations.

current behavior: 

if( step1==false OR
    step2==false OR
    step3==false
  ) check down

desired behavior:

if( step1==false OR
    (step2==false AND step3==false)
  ) check down
