Body: <p>I am writing a program for which I did a My Block. I later realize that I need to add a new input parameter and I can't find a way of doing this without creating a new My Block. This seems it should be trivial but its driving me crazy not being able to find out how. Any help would be very much appreciated. Thanks </p>
