No. On Live after, i dont remember the exact number, 15 minutes i think? Corpses would appear at the graveyard / zone in on any zone. I don't think it's possible for a corpse summoner in the forest to summon corpses cross-zone.
On posting this i realised it's a very short sighted response as people might drag for many reasons.
I personally only tend to drag to get into a spot to be able to rezz my raid in a safe place. If raid is in a horrible place to get back to, it can take a little while to get someone in to be able to rezz (which might happen after several wipes just to recover all the lost exp) but if i could wait 15 mins and all the corpses popped at zone in, i wouldn't need to do that dragging or spend all that time recovering corpses.
But, other people might drag for other reasons. Maybe people purposefully wipe their raids, drag further into the dungeon to bypass a lot of the trash, and then rezz at the boss, or maybe there are other reasons for the drag that a corpse pop at zone in wouldnt address.
As much as I'd like to see the graveyard pop, this particular thread is about auto-consenting not working, so let's not tangent

Ps, if you've never dragged before and find yourself doing it a lot more now, you might be pleased to discover the /corpsedrag command

Maybe /corpsedrag could be increased from 2 corpses to 18 or something? That could be an idea.. drag the entire raid in one go rather than going back and forth... but again.. this is about the consent not working.
