creating Folders in the main menu

[IceDree]

Is it possible to create folders in the main menu (NOT THE HOME SCREEN) to put similar apps in it (I.e. folder titled media to keep music & video apps in it) ?
If its possible please tell me how ?

If it matters :

My phone is :Motorola MileStone
My O.S. is: Android 2.1 (eclair) - stock (not rooted)
I'm using ADW Launcher

Thanks
