If you go into the ordersExport.php file in the admin directory you will see the code below
you can apparently add or delete the database fields to you want displayed in the exported files
and specify the order. You need to replicate it for each form type and you need to add the data field call to each section (line 54):


//all columns:
'v_date_purchased' => $iii++,
'v_orders_status_name' => $iii++,
'v_orders_id' => $iii++,
'v_customers_id' => $iii++,
'v_customers_name' => $iii++,
'v_customers_company' => $iii++,
'v_customers_street_address' => $iii++,
//'v_customers_suburb' => $iii++,
//'v_customers_city' => $iii++,
//'v_customers_postcode' => $iii++,
//'v_customers_state' => $iii++,
'v_customers_country' => $iii++,
'v_customers_telephone' => $iii++,
'v_customers_email_address' => $iii++,
'v_products_model' => $iii++,
'v_products_quantity' => $iii++,
'v_products_name' => $iii++,
//'v_products_options' => $iii++,
//'v_products_options_values' => $iii++,
);

$filelayout_sql = "SELECT
zo.orders_id as v_orders_id,
customers_id as v_customers_id,
customers_name as v_customers_name,
customers_company as v_customers_company,
customers_street_address as v_customers_street_address,
customers_suburb as v_customers_suburb,

ON(zop.orders_products_id = opa.orders_products_id), ".TABLE_ORDERS." zo, ".TABLE_ORDERS_STATUS." zos
WHERE zo.orders_id = zop.orders_id
AND zo.orders_status = zos.orders_status_id

hope that helps..
