Categorize elements in 3ds max?

[Drime]

Hej,
I'm modeling a car in max now but i got lots of diferent ellements.. And i was thinkin is there a way to categorize them?
So you keep different elements but in a category.. By example

Cat name 1 = Wheel
Element 1 = Rim
Element 2 = Tyre
Element 3 = Screws

Cat name 2 = Body
Element 1 = Main hull
Element 2 = Doors
Element 3 = Windows

And so on...

Does anyone know if this is posible and if so how i could do that?

Thanks a lot,
Drime

I am not getting what your saying but if your wanting to work in layers then sure you can do that.

Do you have an example/tutorial of what can be done with layers?? Maybe it is what i'm looking for not sure..
