If your set is big, then yes, it will take a while. It cannot be done automatically but it can be accelerated by using the provided features:
- Press E or press the "Next brick" button (bottom left corner) to automatically select the next brick which has no dependencies
- Use the 1 and 2 keys to toggle between the "Select" and "Dependency" mode
- Toggle on "Smart Cull" (top right corner) to only display the bricks around the selected brick
- Toggle on "Orbit Mode" (top right corner) to rotate the camera around the selected brick
Once you get used to this workflow, it can be done in half the time. Better start with some small sets.
