Sometimes an order gets flagged in the Verify screen due to a phone/address issue, but you know they're valid and want to override the verification and ship it out anyway.
In these situations, you can manually verify any order, it's really easy:
Select the order you want to manually verify
Click on the button with two checkmarks above the orders
You can now proceed with that order, now in the Assign screen
And you are done, your previously flagged order has now been verified and moved to the Assign screen.
