Assistance is needed to minimize annotation effort.

I'm labeling a large synthetic dataset and setting up the required classes to avoid false positives and negatives when detecting defects (red) on turbine blades. To prevent the model from detecting cooling holes (orange) as defects, they need to be labeled as well. However, I'm not sure whether the cooling holes should be labeled hole by hole or as an entire region. This is very time-consuming, and I need the most efficient way to tackle this task. Do you have any recommendations?
thanks a lot for your well needed input :D
