Enable new employees to be added during a pay run Merged

We had an employee who had a payment after leaving, so in order to process the payment we had to open the next pay run early. We then had to add a new employee to the payroll. Because the next pay run was already open she wasn't added to the pay run. I was advised to delete the current pay run and re-open it so that the new employee would be added. This meant I lost a lot of time due to deleting the pay run, it would be far easier if the system could pick up a new employee who has been added during the pay run as this would catch you out many times.
