Make ranged weapon optional when making projectiles

If I want to make a projectile shot by a sword item, for example, I have to create a ranged weapon that will go unused. I could just make it only obtainable through commands, but I don't want to have lots of unused test items come up when I type /give. Could there be an option to create a projectile without creating a ranged item? 

Edit: nevermind i figured out it was in the new snapshot
