Just use the “Listserv command” option from the web interface and enter:
quiet set LISTNAME ack for *@* 
And hit submit. 

You can do multiple settings changes this way like:

quiet set LISTNAME ack,subj for *@*

I can see how to do that for the individual subscriber settings but the list owner wants it applied to all subscribers.  Thank you for an insight into the best way to do this.
