Can u make 1 pbo from several others?

I downloaded some @mod for cars, can i make one @mod with all @mod cars in it?

If yes, is there someone who could explain how?

 

Thanks in advanced...

I wouldn't recommend doing it. Makes it hardier for players to simply join the server without downloading a custom modpack full of everybody elses work. Most use A3 Launcher. And if the mod isn't there or they can't find it on armaholic they tend to just move on to another server.

And you need the permission from all the original mod creators to re-pack their mods and re-sign them, before you are allowed to make that mod pack public.
