As far as I know, it is already doable from the mask of it. What is your situation so that you are not able to change it? Can you share your model as a file?

Try the attached model. Copy the structure and replace it with the pulse generation block. It should work. Instead of writing p inside the constant block, just write the numerical value, 80 or 30.
