Short answer, no. Long answer, er, no. Basically, no. Do not get confused over FPSC terminology and terms used by other tools. Our use of the word PREFAB and SEGMENT are exclusively for explaining the assets selectable from our LIBRARY. You will hear the term prefab in many different camps these days, and they are in no way compatible to the prefabs FPSC uses. There may be a way to get assets from CSHOP to FPSC, though this will likely happen through third party enthusiasm, and only after a while, FPSC is still very new and people are still finding their feet.
