How to different the segments with different color and name in V2

how to different the segments with different colors and names in V2

I’m working on allowing users to paint segmentations on the viewport. I have displayed the segmentation tools in the toolbar and am able to paint on the viewport. In the segmentation panel, all the painting I did on the viewport is combined within one single segment. I’m looking for guidance to be able to paint a second, separate segment (that would have a different color and name)

I haven’t migrated from OHIF v2 to v3. Can this feature be implemented in v2?

Appreciate any inputs.
