Pits/Mass Graves for Corpses/Injured enemies.

[Marauder]

Basically functioning the same way stock piles do, except they'd take less space and allow for injured/downed enemies. As of right now after checking for survivors worth recruiting one has to wait for the others to die from their injuries or put them down one by one by hand.

Instead we could have a type of stockpile/pit/mass grave/ditch in which they get thrown alongside the corpses automatically. It would make burning them all to get rid of the corpses when there is no need for kibble a lot more efficient and quicker.

Mass grave: just build a small room with stone walls, and assign your corpse stockpile there. Then assign a pawn with molotov or inc. launcher to ignite 1-2  corpse.

I think one mod even give you the ability to fire up a special room by flicking a switch.
