Found the answer. The iBook Store customer service rep kindly informed me that this has been an issue recently, and as previously stated, with no remedy yet. HOWEVER, he kindly instructed me to log in to iTunes Connect, using the account the book was created with, select Manage My Books, click on the book you are unable to mass price, select "Rights and Pricing" in the upper right corner of your book page, (if I remember correctly)click on "Add New Territories" on the upper left corner, and WAH-LAH, you now can add all the territories! YAY!
