Undead Meat Wagon - Get Corpse

Anyone found that the Unit - Issue Order with no target doesn't work with the Meat Wagon - Get Corpse?

I've gone as far as eliminating all conditions and ordering a specific unit to Get Corpse, but it doesn't do anything. Surely the unit doesn't have to be under the control of the computer to give it commands?

What I really want it to do is activate Get Corpse to autocast. But there is no command listed for that. Only Get Corpse and Drop All Corpses. But Get doesn't even work.

What is the name of the order that I might be able to paste into the spot where the command name is after converting to custom text?

Thanks.
