Is there a way to use a "save settings button" to have the question "Do you want to change all lines with ....)  automatically answer to NO?
I do not see a "Save Settings button" in SO-A but I just read an old thread that referenced just that.
 
I also skimmed the defaults and did not see an option for this.    
 
 
Thanks Laura
