sbp2 Libraries

How do I store drawings in a library folder in SBP2?
I am using SBP2 to compose an idea for a short 4-5 min animation. It would be great to store characters in the library, which would save me having to copy and paste from frame to frame. I have no idea how to save anything to a library file. Can anyone offer advice?

This is not Storyboard Pro but all TB software shares a similar approach to the Library system. You might be able to utilize the information as it fits the context of SBP:
