Already women's and dance are packaged together as the main event, with men and pairs the undercard.
I think it was always like that. ABC's primetime Nats coverage consisted of the ladies short and free dance (taped) then live coverage of the final group of the ladies' free skate. The only exception was 2006 where they dedicated the entire broadcast to the ladies free skate, choosing not to show any short programs (they aired on ESPN at an earlier date).
