How to Set Confidence Threshold for Prediction, apart from 50/50

Clinton Chee_22047

For classification problem, where the outcome is binary, say Yes or No, and after the Apply Model operator is used, three new columns are created:  Prediction, Confidence Yes, Confidence No.
I'm guessing the default is if Confidence Yes > 0.5, then Prediction is Yes, and vice versa.
Is there a way to set the threshold to be something OTHER than 0.5?
