No, unless they changed it. You put down Coast chioce, then port, and then if sub you put SSN or SSBN (and I guess now you could list SSGN). Coast is the big factor because once you end up on one it can be very hard to get to the other.
PS make sure you are really willing to go to Japan if you pick West coast now, with the GW moving there will more then likely be a lot of billets open on it as I am sure more people want to stay stateside the go there (nothing like a $12 Big Mac UH).
If you want to ensure state side go sub.
