Baum 714XLT Airfeed, Right Angle?

I'm looking at having to fold 11 x 17 sheets of 80# gloss text on my Baum 714 XLT Air Feed folder. The first fold will just be a fold in half, then I have to feed these sheets through again to do a right angle fold for a finished size of 8 1/2 x 5 1/2. The diagram at the end of the stacker calls this a "french fold" (I think). My question is can this thing feed a sheet that's already been folded? 99% of what I do on this is just a letter fold on 8 1/2 x 11 and it works great for that. Thanks.

Hello I'm guessing I might be a bit late but I've only just joined,

Did you manage to resolve this in the end?
