To book on delta.dumb, do a multicity search. You can then compare the fare and even check how much the same fare class would cost without the upgrade.
I'm sorry, I'm not sure what you mean by an upgrade.
I looked at booking the flights online doing it as a multi-city booking, and the fare is about $400 more per ticket, which is definitely not worth it to me. It just seems silly to me that it would cost $400 more simply to take the flight spaced 24 hours a part, but then, it's not as though pricing ever makes any sense.
I just didn't know if there was any way to force a longer layover while booking.
