The type of mods you are saying you want to do can't be done with Horizon or any type of USB/Transfer Cable modding programs, even for campaign. Since auto aim, super jumping, etc, is a modification to the physics of the game, you need to modify it using a JTAG/RGH console. Sorry if this isn't the answer you wanted to hear. But in terms of USB/Transfer cable mods, you can fish around for some sweet campaign game saves, or edit one of your saves to make you have infinite ammo or infinite health, but I'm afraid that's as far as I know of that you can go.
