I have been trying to override a method on wizard in order to add a new parameter, I have created a module that has the same method's name as the one on the module I want to modify, but It is not taking the changes, Do you know how to override only one method on the class that executes the wizard on submit? :

class AccountConsolidationCustom(): 

def get_account_balance(self, account, partner=False, newParam=False):

get_account_balance is the method name inside the wizard script
