JDE BIP Embedded how to display data in 2 columns where the data fills in column 1 first

I found a for-each mod logic to use to get the data in two columns but it fills column A, then B, then column A, then B for next row and so on.  The client would prefer all data go in columns A first and then column B.  How do you do this?  I would attach the attachments for template, XML, and PDF but it wasn't working and it is pricing so need to check with client first.

My current logic has two for each loops

column 1 fields: <?for-each:BIP_Report_S1[position() mod 2=1]?><?end for-each?>

column 2 fields: <?for-each:BIP_Report_S1[position() mod 2=0]?><?end for-each?>
