Management Reporter - Multiple calculations in a Column

Please can someone advise if multiple calculations can be achieved within a Column?

I understand that IF and THEN statements can be used but I have not been able to apply this successfully to my scenario.

For example, I want my Column D to calculate:

If Row number = 110 to 150, then = C

If Row number = 160 to 200, then = C-B

If Row number = 210 to 250, then = B-C

As a workaround, I can achieve this using non-printing rows and column placement. However, it would make more sense to put the formula in the column.

Thanks
