I'm still new to mac. please forgive me if I hit something that is obvious or impossible by design...

I created different folder for each DOS game:

Each game folder contains its own dosbox.app, but I renamed it and changed its icon:

Then I created alias for each game_dir/game.app, until here they all works like I wanted:

Each alias can launch each game using dosbox.

However, in the launchpad only one alias will show. As if the launchpad considers these alias are same. Is it possible to make the launchpad show all aliases?
Thank you

edit: tried using symbolic links but still don't work.
