Making (empty (For adding new parameter)) and (User return variable = (No)) the default values after refreshing sub microflows

After adding a new parameter to a  sub microflow (and it may be used in 200 places) Mendix will request from me to refresh the microflow, and after refreshing it i must fill the value of the ne parameter. I suggest to fill the default value of these parameter to (empty) instead of me filling empty manually at all places that calling this microflow

And the same thing when i return an output from this sub microflow, instead of me saying (No) to the question (User return variable) in all places, make it by default No
