IMO if you can, divide and concur. I use a Lee Loadmaster for all my reloads that has spots for 5 dies so each one has an independent task hence, I body size and neck size independently. I think this method stresses the brass less. Plus I can just remove the body die if I feel there is no need.
What you can do is to neck size only 4/5 times and then you do a full body 1/5.
