Hi,
I don’t know the answer to your question.
The way to determine what you need to do is to first manually set up a presentation so that it behaves exactly as you wish, and then generate the same markup.
If you are not familiar with the technique of using the Open XML SDK Productivity Tool to compare files to identify necessary markup, I suggest watching this video:
How to Research Open XML Markup
This is what I would have to do in order to answer your question 🙂
It is pretty fun to use this technique, identify the changes you need to make, and then generate the presentation with those changes, and see it work.
Cheers, Eric
