Remote MP3 Control

OK,

So I have perfect control of CDJ and my changer via my pronto. (fully indexed album / track list). Now the next step is to be able to select individual MP3's from the remote(pronto).

I could see how I could create a device file, with a map for each mp3, but I would need 100's of IR codes (one for each file). Is there anyway to automatically generate (or does anyone have) a device file and the pronto equivalent with 100's of IR codes?

Alternately, I beleive I could get a way with a few codes, and use something like HASE (http://www.technovelocity.com/hase/), to take multiple codes and use them together to select a song. i.e. [1][5] will play the file associated with 15.

Anybody doing anything like this? Or acheiving the same result through a different method?
