Changing titles of downloaded shows

I did a search on here to make sure I'm not asking what's already been asked.. I found a thread about doing this on a mac, but not PC ...

I have the basic TiVo Desktop .. and the #1 thing I use it for is having my son's favorite shows stored on the PC (so I can download them back onto the TiVO when he requests a specific episode) ... The problem is, on the TiVo, the main list of shows available all show the show name (not the specific episode) .. This means I have to look at each invidivual one to find the one he wants. While not HORRIBLY inconvenient, as it only takes 2-3 seconds to pull up each episode's info, I'd love to make it more efficient.

Is there a way I can change the show name to reflect something else?

Thanks!
