How to "include" Cocos Creator project to Another project?

Hello,
we’re creating some card games (like a blackjack, poker, …) in a Cocos Creator. It’s 1 game = 1 project, so we can export each game to solo app.

And now, we want to create a project “Lobby”, where user can select a game which he want to play. Is there any chance to include a games projects into lobby project and build one big app with all games inside?

Thanks

I think you can export individual scenes when building?
