Name Range - Relative Reference

Hi,

attached you will find a sample..

Could you please help me out, how can i copy the cell C10 to D10 so that name range changes aswell. When copied the formula with Class1 (Range 1) right next it should sum the name range class2 (Range 2)
I know the name ranges are absolute reference and it cant be modified when copied down.
Is there a trick to make it relative Reference.. i want to keep the added Name Definitions untouched.

Thanks
