Organization of the spawn menus

is there a way to organize the spawn menu? It must be possible, such as how by default if you have TF2 then all the prop (ragdolls weapons and other stuff) is all under the prop spawn menu called Team Fortress 3.

Is there a way to do that with the stuff you download? such as I want to put a bunch of prop I got from this site all under the same folder in the spawn menu, but they all come up seperatley named in the menu.

Right click them in the q menu, then ‘Add To Category’.
