Modulising hats and tools?

Essentially I am wondering if it is possible to modulise hats, and or tools in a game. If you have ever created an Image in a game, and opened the game explorer, then looked in Assets/Images then you will find that image, and you will also note that you can access that Image at any place inside your game by referring to "rbxassetid://Image name". And the same scenario for linked source scripts, as you can reference them in the same manner anywhere else in you game world. So what I am wondering is if it is possible to store a bunch of hats and or tools in the game explorer as game assets so that I can access them in any place that is part of my game, or would i have to manually load them into every game via a linked source script? I would appreciate any help; if you don't understand please ask and i will try to explain this better. thanks
