How To Change Default Skin

[Sculpin]

I am in the process of designing a new ( Green Marble ) board for 3DFIBS. Figuring out how to design the board and accessories was fairly easy, but can anyone tell me how to change the default skin which appears at the bottom of the board when you run the program?

I don't think that is possible.. but i could be wrong.
I think it is hardcoded in the software.
