I'm not sure if I like this approach, the public properties in the models are readonly for a reason.
Ones something is parsed it's content and or state should be guaranteed for the code that follows.

And can you add a min example conf so I can see what you are trying to process?

Sure. Im trying to set a reciever address depending on the value of a select box. Looks something like this:

  1 {
    conditions.OR1.AND1 = 1.field=value
    isTrue {
      emailOverride {
        admin {
          toEmail = example@email.tld 
        } 
      }
    }
  }

Im not sure how else id implement that. I dont think the finisher config should handle conditions either, at least not as long as dedicated conditon blocks exist
