can someone make code for tab/enter stops for me please?

[officegirl77]

I've created an Invoice in Excel and I'd like my tab or enter stops to be as
follows:
Start on H7
then go to H8
then B16, C16, D16, E16, F16, G16, H16, I16
then B17, C17, D17, E17, F17, G17, H17, I17
repeating this until last row is
B39, C39, D39, E39, F39, G39, H39, I39

Thank you very much in advance, I really appreciate it!
