automatic add many serial number of a product for sell

[Hydroxy]

When I sold my product I need to add product name then select serial number of product then add to portal table. However, if I want to sell a product in many items, such as 100 items,  it is very slow to add one product's serial to table at a time. Is it possible If I fill quantity to sell and run a script to input amount of serial number, sort ascending, equal to the quantity to portal table ?

 

 

script that I used for now
