I do not want BIAB to choose its own substitute chords or to add notes to a chord not specified in my chord symbols.

How do I shut this off?

In BIAB 2005 (which is where I have been since about 2006) under the big S you could ask it not to add notes to chords, and I like that. Now I cannot find that equivalent feature in BIAB 2017.

Thanks in advance for your help!
