Just wonder why do you need it?

You can add it Address Line 1 and have it on each graph.

@Andrey.Pravdivtsev It is useful to yourself and your colleagues when you are relying on the layout plots shown in design review slide decks and you can see which version of Zemax was used for the analysis. 

It helps in results reproducibility.

@Asuku Thank you for explanation.

On my mind the results should be the same between version. They can be different only if something wrong in the algorithm.
