Adding a Parent Line to a BOM template

I need to modify the standard solidworks BOM template to include a parent line below the header row that autopopulates "PAR" in the Item No. Column, the part number that the bom is associated with in the Part Number Column, and a 1 in the QTY Column.  Currently to accomplish this I am manually inserting a row below the header and typing this information in, then I go back and change the item number sequence from 1,2,3,etc. to PAR, 1,2,etc.  Is there anyway to automate this process?

Thanks for any offered help.

See the examples below.
