Is it possible to Select Item Serial Numbers from a Sales Order?

Our accepted estimates are converted to Sales orders for our warehouse staff to pick. 

How can my warehouse staff select the serial numbers for an item when editing a Sales Order? 

Logically when staff pull an item and have the serial in front of them they update the Sales Order and select the serial.

I understand a serial can be added when creating an invoice but how can accounts team know the serial if the warehouse staff can't select it!

A basic flaw!
