Okay, I did it without removing the DRM. I used the
Mobi2Mobi GUI because my Calibre is setup to remove DRM.
1. I made a copy of the book file and saved it to the desktop
2. I opened the Mobi2Mobi GUI and changed the title and saved the as a .mobi instead of .azw file (just to tell them apart at a glance).
3. I copied the Mobi2Mobi version to my K2s documents folder and viola, I have 2 versions of the book on my K2 without removing the DRM.
