Default Setting to Not Auto Delete Podcasts

Is there a setting somewhere that will prevent podcasts from being automatically elated after being watched by default? I know that I can select the podcast and select "Do Not Auto Delete" from the context menu, but is there a way to set the default? I have to use podcasts as a workaround for the shortcomings of the iPad video app when putting my wife's dance videos into iTunes but I REALLY do not want them deleted!
