A shortcut for changing setting on 30+ programs to: "Until I Delete" ?

I have a Series 3 and a Premiere. Each has about 30+ movies which are scheduled to be deleted this week. Is there a shortcut for changing all of them (i.e., 30 movies at a time) to, "Until I Delete" ... instead of spending 30 mins opening the menu for each movie to change the setting individually?



Thanks much!
