That's a great idea that's been around for a while.
Much like the push/pull that mounts to a gun, I recall about 10-12 years ago a push/pull call that had a stake mounted on it for that very purpose. Not sure, but I think it was Lohman or H.S.
Haven't seen one in a while, guess the idea never gained a following.
