Is it possible to EDIT the show names, and info?

I have a bunch of "Lassie" shows recorded in a folder on my Roamio Basic. Some of them are 3-part shows, and they have the descriptions WRONG as to what's part 1, part 2, and part 3, etc. Or, there's no description at all!

Is it possible to somehow EDIT those to reflect the proper info?
