Default Parameter

AlexKaras I added a keyword test to the execution plan six times, each run with different values for the parameters.  After running the tests a few dozen times realized I wanted to add another parameter.  So I added the new parameter to the keyword test, with a default value, and the parameter for the test items on the execution plan are blank.  But if I add that keyword test as a new child test item to the execution plan the parameter has the default value.  In my mind I thought that since the default parameter value is tied to that keyword test, then it should update in the execution plan automatically, just like if I were to update the value of a test variable, or keyword test step.  I don't understand why we wouldn't want that to be updated automatically.  If I call a function from a keyword test, then add a default parameter to that function, I don't need to update the keyword test to run that function.  It seems like the exact same scenario, but they behave differently.
