Drawing in toon boom studio 4.5

Hi,
I am learning Toon Boom studio (4.5) and am currently breaking a character down. Is there a “create drawing from drawing” selection option. I know in toonboom animate its under edit or f9. It also gives you the option of toogling on/off “cut artwork from source” (not sure if thats it exact wording) any help would be appreciated, thanks
