Opennest linking labels to the mesh

Hi! I’ve been working on creating a 3D object by slicing.
I’ve received big helps from the community, big thanks to @laurent_delrieu.

I’ve cnc machined each sheet based on the labels of each contour nested in the sheet. During assembly, I realized that i’d be helpful to be able to see which contour is which in the 3D mesh(with contours). Things got quite messy since there are multiple contours in each layer, and sometimes the GH reads inner contour as a necessary contour, which makes not all actual contours labeled incrementally to each other. Can anyone help me with this? thanks in advance!

can anyone help me with this? thank you!
