SpreadSheetAddColumn "Insert" differs from ACF

[Leigh-]

Bug\Request
When "insert" is specified, SpreadSheetAddColumn only shifts the replaced cells to the right. ACF shifts the entire column of values to the right.

Actual Results
Only cells A3-A5 (ie "c,d,e") are shifted to the right

Expected Results
All values in column A should be shifted to the right

<cfscript> 
    path  = "c:\testRailo.xls"; 
    sheet = SpreadsheetNew(); 
    SpreadsheetAddColumn(sheet, "a,b,c,d,e"); 
    SpreadsheetAddColumn(sheet, "1,2,3", 3, 1, true);
    SpreadSheetWrite(sheet, path, true); 
</cfscript>
