I figured out a way to do this by making 2 parameters in an action list and swapping them based on the check and set parameter action list type actions.
So my interaction starts with a check parameter for a "wetalked" parameter which I created in an action list which defaults to false.
At the end of your first convo you can create a new action to "setparameter" and you can take your "wetalked" and set the "new value is:" to "copied from parameter" and reference the second parameter created which defaults to "true"

Once text has been gathered, the option "Only say once?" should appear in a speech line's entry in the Speech Manager.
What is your AC version?
Hey, I am having the same issue, using 1.76.1 and I do not see that option anywhere.

It should be visible for speech text entries listed in the Speech Manager.
