Add a new employee to a payrun that has been reopened Merged

If a payrun is reopened due to adding a new employee, Staffology should have the ability to include this employee to the that particular payrun. Currently, you have to delete the reopened payrun and start from zero to ensure the inclusion. What if you have 100 employees with various pay elements? I know you have import facility but wouldn't it be easier to add this new employ to the payrun instead? Makes more sense and saves time.

Thank you!
