A possibility to put your *.wdl files in a different folder then the workfolder like;
Gstudio6
..Workfolder1: all the WED elements and Start.wdl for that game (1)
..Workfolder2: all the WED elements and Start.wdl for that game (2)
..etc.
..Scriptsfolder: all the scriptfiles needed for game1 and game 2
In this way, if you change a wdl file, it will effect all the games where it is used and the gamefolder in use has no elements that are not needed by the game.
