WGS sequences through Bio::DB::GenBank

I know that a recent post showed that you could retrieve CONTIG sequences
from GenBank files fairly easily:

I'm driving myself a bit buggy looking for this, and I may be blind to it,
but can the same be done with WGS files?  I've tried Bio::DB::GenBank and a
few other Bio::DB* modules to see if it's been implemented but haven't had
any luck yet.  I may try getting around it using Bio::DB::Query::GenBank,
but just trying to find a more direct route.
