BOM Ballooning

Hello,

I need to do ballooning of all parts in a drawing view. For this, I have generated BOM table from Table--->Quick Table--->BOM DESCRIPTION Down.

After that, I selected SWITCH SYMBOLS and I am able to see a parameter named as rpt.index under ITEM column of BOM table.

I would like to know how to modify this parameter for the different parts?

Thanks and Regards'
