Ahhhh ...
You merely need to adjust your thinking slightly. Since the Disposition isn't available until the End of the call, the Vicidial system cannot determine that a new lead should be placed in a list at the beginning of a call with information that is not yet available.
However, there is a special campaign (and Ingroup) setting for "Dispo URL". This can include a script that will move the lead based on disposition. There are several examples of this available on the forum.
I would hesitate to go further until I hear the reason you want to move a lead to a new list based on the disposition. Often what you are trying to accomplish by moving the lead can be better accomplished a different way. (not always, of course, just "often"

)
