According to this post (note that this is 3 years old), you can assign all shading surfaces to a single shading group. The main reason you would use different shading groups within one OpenStudio model would be to:

You should know that external shading surfaces like overhangs and fins will only affect the model if the Solar Distribution input field of the Building object includes external surface interactions. You can read more about that here.
