When programing new shows, just make a pallet for each library and file, this way when ever it appears in the programer or contents window it is words not number that can be many characters long. This can be a little tricky when you have hundreds of clips, but a little organization makes this quite easy. You can also use programs like iView Media pro to manage all you media.

I know it is not what you are suggesting, but it is a quick fix.
