Can I add to the CAG game database?

Hi,

  Is there a way that I can add missing games to the CAG game database?  For example, the game "The Cave" for Xbox 360 (XBLA) does not seem to exist in the CAG game database.  It is there for PC, PS3, etc, but not for XBox that I can tell.  I saw how to edit an existing entry, but not how to add a new one.  I am under the impression that there is a unique database entry for the game on each of the consoles.  Is this correct?  

Thank you for the help.

Bump.  This is one of several features that we lost after the site upgrade downgrade.  Is this ever coming back?  And what about price notifications? I wish they could just roll back to the old site it was so much more functional.

Rayman Legends for the Xbox One is another one of many games missing from the list.
