Because of the way the OptimizePress LiveEditor works, there isn’t a way to batch convert pages.
The main reason for this is because each page has independent content areas – i.e. you can place content anywhere you want on the page , so for example one page might have a 3 column layout with content in each column, then a 2 column layout etc – you get the idea
Because of this – a batch conversion system (if one were created) would have no way to know which content should go where on a new page – so it would be very complex to make something like this work effectively and accurately.
