custom show names or alias

Hi, I'm hoping I can get some help here!!
I have a pretty slick setup, where my torrent client automatically downloads my weekly shows, and then I have a program that automatically scans the download folder, renames everything, and moves it, and then calls XBMC through a web interface to update my library.

I am trying to simplify my *monsterous* batch file that sorts everything, and have stumbled across this *great* program(love tvrename so far!!!!)

however, I am having real problems with shows like CSI... xbmc only scans it properly if the show is titled Crime Scene Investigation... it downloads as CSI.SxxExx.groupname.avi

Now, If I set it as a custom show name such as CSI, tvrename will find it, but renames it as "CSI SxxExx - title"

how can I get it to find it as CSI.xxxxx and rename it as "CSI: crime scene investigation xxxxxx"???
please help, I am a decent programmer, so If it is an update we need, someone please help point me in the proper direction!!!

on the setup of each show you can specify a custom name and also alias' to search for.

Go to any show in the left hand pane of the shows tab and right click - edit show. just below the show list in the middle of that pop-up window is the place to put in your custom name.
