How do I enable by default confidence diamond in box plot within Graph Builder?

[#1]

I'd like the confidence diamond to appear automatically every time I add a box plot in the Graph Builder, i.e. make confidence diamond a default for a box plot in Graph Builder. How can I do this?

If you are able to do JSL scripting, it can be done.

But, if using GUI, I didn't see the options to tick "confidence diamond" preference in Graph Builder - probably because graph builder functions has many type of charts.

Is running a custom script much faster than selecting Confidence Diamond option for box plots?
