You can, but it's mainly up to you to make the pieces.My workflow:
1. clone the object that I want to fracture.
2. open the image editor and draw lines on it to split it up into parts.
3. duplicate that frame for every part.
4. Then I edit each duplicate frame and erase each other part off the image.
5. Adjust the collision polygons and crop. (don't touch the origin point)
6. After that I had to click the Make 1:1 to fix the scale.
Btw how did you erase parts of the image? The only way I can see is with the eraser, but i cannot draw lines with it
