I am sorry but that's not possible. Our IF ELSE blocks can only use another one of our non-coded verification steps as the IF condition. Further, our non-coded verification steps can only verify some property of some UI element present in the application (or verify an element is no longer present).
To achieve the same effect requires you to implement the entire IF ELSE block in a coded step. One thing you can do in a coded step is call another test using our Test-as-step feature using code like this:
This way you don't have to convert all your steps into code. Instead put the contents of the IF and/or ELSE block into a separate test then call it as a sub-test.
