it never existed iirc, but you can add it with bindatcommand and
getinventorylist;
for( set .@i,0; .@i < @inventorylist_count; set .@i, .@i + 1 ) {
if ( @inventorylist_identify[.@i] == 1 ) continue;
delitem2 @inventorylist_id[.@i],1,0,0,0,0,0,0,0;
getitem @inventorylist_id[.@i],1;
}
I don't really think devs should add this
