Would like to know if there is a way to transfer my files from iBooks to PDF studio

Organizing, Reading and Booking are great. How about Annotating PDF's?

I purchased this app a while ago along with Scrivio Pro which I use all the time and love. I just recently started using the app and have found the organizing, reading, book marking and the zoom feature to be great. I really would love to see the incorporation of being able to annotate PDFs files. This really is a must as we move further and further away from pen and ink. I am willing to pay more for this feature, especially if it works as well as the other aspects of the app. Thank you for the good work thus far.
