No, the default setting is not user selectable.
I'd prefer the once option myself
Maybe DIRT could put in the request for us.
unless its a syndicated show then it defaults to all
but honestly this is one complaint I had when I started with Dish. Directv is simple
one hit of record button to record that show
two to record the series (which has the defaults already...default is new)
No extra menus to go into to set up a recording like with Dish
