Ghosts- Private Match- Knife only

A bunch of my friends and myself wanted to play a knife only private match but we can't figure out how to setup the game for that.
We keep getting our each individual default loadout even after using loadout restrictions and only having combat knife available.

Anyone have any idea how to set up a game like that? Or if it's even possible.
We would like it to be a FFA, but I thought Domination would be interesting also. Combat knife- MAYBE a 44 Magnum- no lethal or tactical and set perks (agility, marathin, etc..).

It would be under game settings.

yeah there's nothing there to set it up like that. Not that I see anyway.
