Here is an image of the segmentation that I want to do. I want to be able to paint outside the invisible box that seems to define the bounds of the segmentation, but am not sure how to expand it to include the entire image.

Any help would be really appreciated, thank you!

[This section](https://slicer.readthedocs.io/en/latest/user_guide/modules/segmenteditor.html#cannot-paint-outside-some-boundaries) of the Segment Editor documentation should help.
