Creating automated source cell ex. [(R3 +R1) * R7]

[GoUmass]

In my company's reports we often have a source column that lists the formulas pertaining to the cell next to it.

example

Row item value source
[TABLE="width: 510"]
<tbody>[TR]
[TD]9[/TD]
[TD]Total Market Value of Assets[/TD]
[TD]xxxx[/TD]
[TD](R7 + R8) * R2[/TD]
[/TR]
[TR]
[TD]10[/TD]
[TD]Difference[/TD]
[TD]xxxx[/TD]
[TD]R9 - R6[/TD]
[/TR]
[TR]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]11[/TD]
[TD]Enterprise Value from Multiples[/TD]
[TD]xxxx[/TD]
[TD]R1[/TD]
[/TR]
[TR]
[TD]12[/TD]
[TD]Total Market Value of Assets[/TD]
[TD]xxxx[/TD]
[TD]R7 + R11[/TD]
[/TR]
[TR]
[TD]13[/TD]
[TD]Difference[/TD]
[TD]xxxx[/TD]
[TD]R12 - R6[/TD]
[/TR]
</tbody>[/TABLE]


Is there a way to write a VBA function that will automatically write that source of the referenced cell, and update it if the row number changes? meaning that it will look at the calculation in the cell and then replicated it using table row numbers.

Note, the source cell is referencing the Row # of the table, not the row # of the spreadsheet... such that table row 10 could be excel row 50.

Thanks for the help!
