Automatic rotation during tethered shooting

Hello,

I use a Canon 30D and no Phase One Back. If I make a tethered shooting and I know that I just will make photos with vertical orientation (I do not know the englisch word for that) it would be good to get them rotated automaticaly. I tried several things but could not find a way to get that.
Does anybody know a solution for that?

Thank You,
Joachim
