Add double underline to row

I am trying to add a double underline into a specific row (Cell "A" & row). The row can change so I cannot code the position. Initially I had the text coded with a double underline, but my user wants some space between the text and the underline, which led me to try using the shape object. How would I change the following code:

With Sheets(shtRpt).Shapes.AddLine(0, 100, 132, 100).Line
                .Style = msoLineThinThin
                .Weight = 3#
            End With

Thanks.
