Hello, if I am using the segment editor module and I have multiple segment layers of different portions of an image, is there way to create a new segment layer that will combine all of the portions? For context, I want individual segmentations and then an overall segmentation of the whole structure without overwriting the previous segments or having to manually draw over the previous segmentations?

You can use “Logical operators” effect to combine segments.

Alternatively, you can use Paint effect with masking. For example, to repaint all visible segments by selecting “Editable area” → “Inside all visible segments”.
