Allocation option „Partyleader with Short allocation“

Hey you PoE people
A big thing in endgame mapping is Groupfarm or some kind of „Level Service“.
But with a full group of random leechers, sometimes the loot I want as a „leveler“ randomly disappears on a mysterious way. *ironyoff*
Maybe we could implict another Allocation option as said in the Titel, every loot is for the partylead and After some seconds everything is FFA.
