Keeping duplicate apps out of my iTunes library

[Sossity]

when I upgrade from a free version of an app to a pro version, I notice that I am left with the free version and the upgraded version in itunes, is there a way to consolodate and have just the pro upgraded version of the app?

Since Apple doesn't allow or have provisions for App testing they are two totally different apps offered by the same developer. You can just delete the free version.
