Can you please flag anyone on a PvP server for PvP while inside a PvE dungeon thats entrance is located in a Contested zone?

Currently if someone releases and is running back, they can not be ressed by targeting a gravestone due to being PvP flagged 'cause they're running through a contested zone and those inside are not flagged. There's numerous other issues that crop up with this, but this is one of the more annoying ones.
