AimOffset Blend

Hi, i make an AimOffset to set the positions of the gun aiming, works fine and i´ve be able to blend it with reload and shoot animations too, but my question is if its possible to blend that AimOffset to use Knife position instead of gun position or i have to make different AimOffset asset for each weapon? (GunType, ShootgunType, Rocket Launcher, Knife,…)

Thanks
