Sales invoice items needs

when i want to print sales invoice there is description in every row of items i will sale i want it equal to item name in inventory items which i already added it before i make the invoice
also the same thing in purchasing invoice
last ask i want serial numbers at every row at sales invoice and purchasing invoice (1,2,3,4,5,6,7,…) not limited

Here is a comment from another topic

“Item name will never show on invoices. It is your internal name of the item. Only code and description of the item will show. Why not add item name to description if you want to show it to customer?”
