Add line item numbers to sales order/invoice creation page

Add line item numbers to sales order/invoice creation page

It would be really helpful if there were line numbers visible as we are creating a sales order and/or invoice. There are line numbers visible in the PDF once the sales order is created. I would like to be able to see the line numbers as I am building the sales order. We have many sales orders with 50 or more lines. The items we sell contain lots of small parts that go with the larger system and many of these parts are very similar in name and SKU, they may just be 1/8 inch larger than the part above so it can be very difficult to determine which item you need to address because the names are so similar. Having a line number to look at would ensure that we are addressing the correct item. We have had a couple of instances of addressing the wrong line and it has cost us to have to reship items and has angered some customers. 
Community please support this idea so that hopefully we can have this addressed by Zoho
