Can you save "toy box add ons"?

Well, Some of the toybox mods are some of the best.
Im wondering if i can save them to my pc so i dont have to go download them every time.

Example : When I open my weapons section, I want a gun i downloaded from toybox to be there.

There is some info on the following link, Im sure you can figure it out :>
