How to keep My Digital Editions folder on OneDrive

I keep all my user files on Microsoft OneDrive so that I can access them from my desktop and laptop computers. I would like to do the same for the 'My Digital Editions' folder which currently resides in My Documents on the C:drive.  I can see no way to direct the Digital Editions program to  the corresponding location on OneDrive.  Is there a way of doing this?

Both computers are running Windows 8.1.  The same question would arise with GoogleDrive or DropBox of course.
