Can i copy a homebrew adventure ?

Im not sure im saying this right in the topic. So, i can "create a new game" and then select a module to run like lost mines.  My question is can i create a campaign that i can save as a module and then later create new games using it?  basically i want to be able to run my creation with multiple groups and not have to create the same thing twice.  its probably something obvious but im not seeing it.  

You can achieve that functionality by creating a game to use as a base, then creating copies of it. When you go to the Game Details page for the base game, click the Settings menu and choose Copy Game. 

that is EXACTLY what i was looking for. thanks!
