Currently the workflow requires a user to input the Start Station, End Station, Start Value, End Value for any variable constraint override. In my experience, 95% of the time this override is constant for the entire length of the element. It would significantly save time to have the program default to a 'constant value', requiring just one input. You can keep the current workflow in case the variable varies or has a unique start/end location. I recommend a toggle for a 'constant variable override' (yes/no).
