Customize a Report Parameter's default value in Kinetic

Does anyone know how to customize a default value on a Report Parameter in Kinetic? In Classic, I can use the Customization Tool > Customization Code Wizard > Extended Property Wizard but not seeing how to do something similar in Kinetic.
I am trying to set the “Print Comments” on the Methods Master Report so that it is always checked. Screen shot below shows how I can do this in Classic.
