Q: I cannot add empty partitions

My original mission was to extend the size of my bootcamp partition, but since resizing is not possible on Yosemite, I just decided to save everything on an image file using WinClone. I have this, no problems.

My issue is that I can't add empty partitions. As seen in the picture, this option is greyed out. If I had such a partition, WinClone would allow me to put all my content back onto the partition.
